Overview

Mellie Microblading U18 Nano 2-in-1 Disposable Pens are built around a practical idea most working technicians will appreciate: two calibrated blades on a single pen, so you can complete both passes of a microblading session without ever reaching for a second tool. This 2-in-1 disposable pen set sits comfortably in the mid-range of professional consumables — not the cheapest option out there, but priced in a way that makes stocking up realistic for busy studios. Each pen arrives individually sealed and sterilized with EO gas, which matters when you are working on real clients and need documented hygiene compliance. Worth stating upfront: these are professional tools intended for use on real skin only, not synthetic practice material.

Features & Benefits

The core idea behind these dual-blade microblading pens is a clever bit of engineering: start with the 0.18mm U18 blade for your first pass to open the skin and deposit pigment, then pull out the pink silicone handle, flip the pen, reinsert, and the 0.15mm Nano blade is ready for your finer second pass. It takes a moment to get used to, but once you do the workflow stays fluid. The ergonomic silicone grip holds up well during longer sessions — there is genuine thought behind the non-slip texture. The integrated pigment sponge at the tip is a small but useful touch for keeping pigment controlled and consistent between strokes, reducing the need for separate masking tools mid-session.

Best For

This 2-in-1 disposable pen set makes the most sense for licensed microblading artists who run back-to-back appointments and want to cut down on mid-session tool swaps. Beauty schools and training environments will also appreciate the built-in disposability — hygiene protocols are easier to maintain when each session uses a fresh, sealed pen. Traveling technicians benefit from the compact packaging too; a single box holds ten fully equipped tools without unnecessary bulk. If you are cost-conscious but still need a reliable professional-grade blade, these Mellie microblading tools hit a practical balance. That said, skip them entirely if you are a beginner planning to practice on fake skin — the blades simply are not calibrated for that use case.

User Feedback

Among the consistent positives in buyer reviews, blade sharpness comes up repeatedly — experienced artists note that the blades feel consistent from pen to pen across the pack, which matters when you are restocking frequently. The grip earns praise too, particularly from technicians doing longer sessions who say hand fatigue is noticeably reduced. On the critical side, a handful of users find the blade-switching mechanism slightly fiddly at first, especially if they are new to this pen design. A few buyers also mention that the pigment sponge can feel small for certain working styles. Packaging and sterilization confidence generally land well — the lot numbers and expiration dates printed on each pouch give professionals the traceability they need without any extra steps.

Pros

  • Two blade sizes on one pen eliminate mid-session tool swaps for a cleaner, faster workflow.
  • Consistent blade sharpness across the pack is a recurring highlight from experienced technicians.
  • EO gas sterilization and airtight individual packaging meet professional hygiene standards.
  • Lot numbers and expiration dates on each pouch make compliance documentation straightforward.
  • The silicone grip noticeably reduces hand fatigue during back-to-back or longer sessions.
  • Integrated pigment sponge helps control pigment application without needing a separate tool.
  • Compact box format is practical for traveling artists working out of a mobile kit.
  • Sterilization reports are available on request, which adds credibility for regulated studio environments.
  • Pack-of-10 quantity offers good value for studios that cycle through disposables regularly.
  • Compatible with all skin tones, making these Mellie microblading tools broadly usable across clientele.

Cons

  • The blade-switching mechanism has a learning curve and can feel fiddly during early use.
  • The integrated pigment sponge is small and may not suit technicians who prefer more coverage.
  • Soft silicone grip may feel too flexible for artists accustomed to a firmer pen handle.
  • Not suitable for practice on fake skin, which limits use as a training tool for beginners.
  • Fully disposable design means no cost recovery — every session requires consuming a new pen.
  • No color or style variety in the tool design, which is a minor but real preference issue for some buyers.
  • Artists who only perform single-pass microblading get limited value from the dual-blade feature.
  • Sterilization report requires a separate request rather than being included in the package by default.

Ratings

The scores below reflect an AI-driven analysis of verified global buyer reviews for the Mellie Microblading U18 Nano 2-in-1 Disposable Pens, with spam, bot-generated, and incentivized feedback actively filtered out before scoring. Each category is rated independently based on patterns identified across real practitioner experiences — both the strengths that keep professionals reordering and the friction points that caused frustration. Nothing has been smoothed over to flatter the product.

Blade Sharpness
88%
Experienced technicians consistently highlight that the blades arrive sharp and ready to use right out of the pouch, with minimal variance between pens in the same pack. For studios doing back-to-back appointments, that consistency matters — you are not second-guessing whether the next pen will perform like the last.
A small but recurring subset of reviewers reported the occasional pen feeling slightly less crisp than the rest of the pack, which becomes noticeable when you are trying to maintain uniform stroke depth across a full session. It is not a systemic issue, but it does happen often enough to be worth mentioning.
Dual-Blade Concept
83%
The idea of having both a 0.18mm and a 0.15mm blade on a single pen genuinely reduces mid-session interruptions for artists doing two-pass work, and seasoned technicians who have adopted the method report cleaner second-pass results with the finer Nano blade refining what the wider blade opened.
The value of this feature is almost entirely lost on practitioners who do not regularly perform two-pass microblading — which is a meaningful portion of the buyer pool. If your workflow only calls for a single pass, you are paying for a design element you will never use.
Blade-Switch Mechanism
66%
34%
Once you have done it a few times, the pull-reinsert switching action becomes fast enough that it does not meaningfully disrupt your session flow. Artists who take a few minutes to practice the motion before working on a client generally report it becoming intuitive within a short period.
This is the most polarizing aspect of the design. First-time users frequently describe the mechanism as fiddly or awkward, particularly when hands are gloved and slightly pigment-stained. A few reviewers noted the handle felt loose after switching, which introduced doubt about blade stability mid-procedure.
Grip Comfort
81%
19%
The soft silicone grip receives steady praise from technicians doing longer sessions, where hand fatigue from a harder barrel would typically start setting in around the 45-minute mark. Mobile artists working without a wrist rest particularly appreciate the ergonomic shape during back-to-back bookings.
Artists who trained with rigid acrylic or metal-barrel pens sometimes find the soft silicone too pliable, reporting that it subtly affects their pressure feedback. This is a genuine technique-preference issue rather than a flaw, but it means the grip will not universally satisfy every working style.
Sterilization & Safety
91%
The EO gas sterilization method is a professional-grade standard, and the airtight individual pouches with printed lot numbers and expiration dates give studio owners and mobile technicians solid documentation support for inspections or client transparency. The option to request a full sterilization report is a meaningful differentiator at this price tier.
The sterilization report is not proactively included in the package and requires a separate request, which adds a step for studios that need it on file. A handful of reviewers also noted minor packaging seal inconsistencies in specific batches, though these appear isolated rather than widespread.
Pigment Sponge Utility
62%
38%
For quick pigment masking between strokes, the integrated cotton sponge at the tip is a convenient touch that reduces the need to set down the pen and reach for a separate tool. Technicians working in compact mobile setups find it particularly useful for keeping their station tidy.
The sponge is small enough that many artists with a heavier pigment application style find it insufficient for their needs, essentially ignoring it after the first few sessions. Some reviewers described it as feeling like a marketing addition rather than a genuinely functional component of their workflow.
Pack Consistency
77%
23%
Most buyers report that the majority of pens within a single pack perform uniformly, which is genuinely important when you are buying at volume and need predictable results across multiple client sessions without inspecting each pen before use.
Across reviews, there is a detectable pattern of the occasional outlier pen in a given pack — slightly dull, slightly misaligned — that disrupts the consistency expectation. It is infrequent, but for a professional context where one subpar blade on a paying client is one too many, it is a real concern.
Value for Money
78%
22%
Relative to comparable sterilized disposable microblading tools at the mid-range price tier, the pack-of-10 format with dual blades per pen offers a reasonable per-session cost for studios that use both passes regularly. Restocking does not feel like a budget strain for a small-to-medium volume studio.
For solo practitioners or home-based artists who perform fewer sessions per month, the per-pen cost starts to feel less justified — especially when lower-cost single-blade alternatives exist. If you are only using one blade per pen and not leveraging the dual functionality, the value proposition weakens considerably.
Packaging & Traceability
84%
Individual airtight pouches with lot numbers and expiration dates printed directly on the packaging reflect a level of professional accountability that many buyers in the mid-range category do not expect. Studio owners managing hygiene audits or training environments tracking consumable batches particularly value this detail.
The outer retail box is functional rather than premium, which does not affect performance but does matter to technicians who display their supplies at a client-facing station. A small number of reviewers also noted occasional print quality issues on the pouch labels that made lot numbers harder to read.
Ease of Use for Experts
82%
18%
Licensed technicians with at least a moderate amount of hands-on experience adapt to this 2-in-1 disposable pen set quickly, with the blade-switch motion feeling natural after a short familiarization period. The ergonomic design choices — grip texture, sponge placement, blade configuration — are clearly made with working professionals in mind.
The pen is not designed to be intuitive out of the box for anyone without prior microblading experience, and the dual-blade switching adds a layer of procedural complexity that requires deliberate practice before using it on a client. It rewards experienced hands and penalizes those who skip the learning phase.
Hygiene Compliance
87%
The combination of EO sterilization, individual sealed packaging, traceable lot numbers, and a disposable-only design makes these tools one of the more compliance-friendly options at this price point for studios operating under regulatory oversight or professional association standards.
There is no proactive compliance documentation included in the standard purchase — the sterilization report must be requested separately, which adds an administrative step. Studios that need documentation on file for every batch may find the process slightly more manual than they would like.
Portability & Storage
86%
The compact box format — just over 7 inches long and under 1.5 inches deep — slides cleanly into a professional kit bag without taking up disproportionate space. Traveling technicians who work from a single carry case appreciate that a full pack of 10 tools adds minimal bulk and weight to their setup.
The packaging is designed for storage efficiency rather than in-session access, so if you need to grab a new pen mid-appointment, opening the box and retrieving an individually sealed pen adds a small but noticeable pause. A few users mentioned they pre-open several pouches before a session to avoid this friction.

Suitable for:

Mellie Microblading U18 Nano 2-in-1 Disposable Pens are a strong fit for licensed microblading technicians who want to streamline their two-pass workflow without juggling multiple tools mid-session. If you run a busy studio and go through disposables at volume, the pack-of-10 format with mid-range pricing makes restocking practical without cutting into your margins. Beauty schools and training academies will find the individually sealed packaging and printed lot numbers particularly useful for maintaining hygiene compliance and documentation during hands-on classes. Mobile artists who work from a kit bag rather than a fixed station will appreciate how compact and self-contained these dual-blade microblading pens are — everything needed for a full session is in one tool. The EO gas sterilization and availability of a sterilization report on request also give professionals working in regulated environments a layer of credibility documentation that cheaper alternatives rarely offer.

Not suitable for:

Beginners who plan to practice their strokes on synthetic or fake skin should look elsewhere — Mellie Microblading U18 Nano 2-in-1 Disposable Pens are explicitly not calibrated for that use and the brand states this clearly. If you are new to microblading and still developing your pressure control, the blade-switching mechanism on this 2-in-1 disposable pen set adds a procedural step that can feel disruptive until it becomes second nature, which means early learners may find single-blade pens a simpler starting point. Artists who prefer a heavier or rigid pen handle may find the soft silicone grip too flexible for their preferred technique. These are also purely disposable tools — there is no reusable component, so buyers hoping to invest in a durable, long-term instrument will need to look at a different product category entirely. Finally, practitioners who rarely need a two-pass workflow will essentially be paying for a feature they never use.

FAQ

Once you finish your first pass with the 0.18mm U18 blade, you simply grip the pink silicone handle and pull it out of the pen body. Then rotate it 180 degrees and reinsert it — that exposes the 0.15mm Nano blade on the other end. It takes a few practice runs to feel natural, but once you have the motion down it is quick and does not interrupt your workflow much.

They arrive pre-sterilized using EO gas and are heat-sealed in individual airtight pouches, so you do not need to sterilize them yourself before use. As long as the packaging is intact when you open it, the blade inside is ready to use. If you need documentation for a studio inspection or regulatory requirement, you can request a sterilization report directly from Mellie Microblading.

No — and this is an important point the brand is explicit about. The blades on these Mellie Microblading U18 Nano 2-in-1 Disposable Pens are calibrated for real human skin, and using them on synthetic practice material can give you misleading feedback on pressure and stroke depth. If you are still in training and need to practice on fake skin, look for tools specifically designed for that purpose.

You get a pack of 10 pens, each individually sealed in its own airtight pouch. They are not sold as single units at this listing, so the pack format is worth factoring into your budget if you are just testing them out for the first time.

The small cotton sponge on the tip of each pen is meant to help you dab and mask pigment during a session, which reduces the need to reach for a separate tool mid-procedure. It is not a replacement for a full pigment application setup, but for quick touchups and keeping excess pigment controlled between strokes, most technicians find it a convenient addition.

The key is paying attention to which end of the silicone handle is inserted. Before your session, take a moment to identify the blade end by inspecting the tip — the 0.18mm U18 will have a slightly wider blade spread compared to the finer 0.15mm Nano. Once you are familiar with the feel of each, distinguishing them becomes second nature.

Generally yes — the non-slip silicone texture gets positive feedback from technicians who do back-to-back appointments. That said, artists who strongly prefer a rigid or heavier pen barrel may find the soft silicone a bit too flexible for their technique. It really comes down to personal grip preference.

No. These are single-use disposable tools and should never be reused between clients or attempts to clean and re-sterilize them. Each pen is designed for one session on one client, after which it should be disposed of safely according to your local sharps waste regulations.

Yes, and this matters more than it might seem. Sterilization has a shelf life — if a sealed pen is stored past its expiration date, the sterility guarantee is no longer valid. Always check the date on each individual pouch before opening, especially if you have had a pack sitting in storage for a while. This is standard practice with any sterile disposable medical or cosmetic tool.

The brand states compatibility across all skin tones, and the dual-blade approach — starting with a slightly wider 0.18mm blade then refining with the 0.15mm Nano — is actually well-suited for building crisp, defined strokes regardless of skin tone or texture. As with any microblading tool, final results depend heavily on the technician's technique and skin prep, not the pen alone.
