Complete guide: Tattoo Needles Kwadron Cartridge PMU OPTIMA RL Long Taper
These are single-use cartridges designed for micropigmentation (permanent makeup), in a Round Liner configuration with a long taper — Long Taper (7 mm) — that penetrates the skin gradually and with great control. They are intended for PMU technicians performing hair strokes on eyebrows, fine eyeliner, or lip contour, but they also fit standard tattoo machines with a cartridge system for fine lining. Each cartridge is individually sterile sealed, and the price shown is per piece.
How to use
- Check the integrity of the sterile blister before the procedure — if the packaging is damaged or unsealed, do not use the cartridge.
- Wash your hands, put on disposable gloves, and prepare the work station with protective barriers (plastic wrap on the pen/machine, cable cover, clean work area).
- Remove the cartridge from the blister directly into the clean work area and mount it into the PMU pen or the machine compatible with the cartridge system.
- Adjust the needle protrusion to the value suitable for your technique — in permanent makeup, work superficially with short, controlled movements.
- Set the power supply to low voltage — the manufacturer's description recommends approximately 3.5–5 V for hair strokes with this series — and check the needle movement before touching the skin.
- Build the lines one by one, periodically wiping excess pigment from the tip with a clean, disposable tissue.
- At the end, remove the cartridge and immediately dispose of it in a dedicated sharps container; do not reuse it under any circumstances.
- Disinfect the pen, power supply, and work surfaces according to the studio's hygiene protocol.
Tips from us
- Choose the configuration according to the procedure: in this series, the description mentions 1RL for ultra-fine hair strokes, 3RL as a versatile option for standard hair strokes and fine eyeliner, and 5RL for lip contour.
- Let the Long Taper geometry do the work: the long taper penetrates gradually, so do not compensate with high pressure or high voltage — on the thin skin of the face, less is more.
- The cartridge membrane prevents backflow of pigment and fluids to the pen — but it does not replace protective barriers and basic hygiene on the equipment.
- Keep a small backup stock: as a single-use consumable, you need a new cartridge for each client and for any cartridge dropped or contaminated during work.
- Record the packaging information (batch, series) in the client's file — traceability is useful if questions arise after the procedure.
Warning: The cartridges are sterile and strictly single-use: one cartridge = one client = one procedure. Do not resterilize or reuse a cartridge, even for the same client at a later session. Check the sterile seal before each use and dispose of used needles exclusively in sharps containers. Work only with gloves, on properly cleaned and disinfected skin — permanent makeup must only be performed by trained technicians in authorized facilities.
Frequently asked questions
Does this cartridge fit my machine?▾
The manufacturer's description specifies compatibility with PMU pens and standard tattoo machines that use a cartridge system. If you work with a specific pen, check its manual to ensure it accepts standard format cartridges before ordering.
What do RL and Long Taper actually mean?▾
RL stands for Round Liner: the needles are grouped in a tight circular formation for lining. Long Taper means an extended needle taper — here 7 mm — which enters the skin gradually, not abruptly. The combination offers fine control, which is why it is preferred in micropigmentation, where work is done on delicate facial skin.
Can I reuse the cartridge if I disinfect it well?▾
No, absolutely not. The cartridge is individually sterilized and designed for single use. Reuse — even after disinfection — poses a real risk of infection and pathogen transmission, because a used needle cannot be properly resterilized in studio conditions. After the procedure, the cartridge goes directly into the sharps container.
I'm new to PMU — which configuration should I choose?▾
According to the description, 3RL is the most versatile option for permanent makeup in general (standard hair strokes, fine eyeliner), so it is a reasonable starting point. 1RL produces the finest lines but requires more control, and 5RL is mentioned for lip contour. Choose based on the procedures you do most often.
Is the price per box or per piece?▾
According to the product description, the price is per piece. Calculate your needs based on the number of procedures — you need at least one new cartridge per client.
Can I use these needles for classic tattoos as well, not just permanent makeup?▾
Yes, in principle: Round Liner is a standard liner configuration, and the description mentions compatibility with standard tattoo machines using a cartridge system. However, the series is optimized for micropigmentation — the long taper and low voltage work make it suitable especially for fine and delicate lining, not for shading or thick lines.

Kwadron PMU Optima RL Long Taper cartridge needles are premium Round Liner needles with a long taper point, designed for maximum precision lining in permanent micropigmentation. The RL configuration arranges needles in an ultra-tight circular formation, and the Long Taper provides an elongated point geometry enabling extremely controlled and delicate penetration. This combination is ideal for individual eyebrow hair strokes — each line is fine, precise, and natural, perfectly imitating natural hair. Manufactured in Poland from 316L surgical stainless steel with Kwadron's premium finish, these needles offer a microscopic polish that reduces facial skin trauma to a minimum. Kwadron's advanced-generation safety membrane completely prevents pigment and biological fluid backflow. Individual EO gas sterilization and blister packaging guarantee maximum safety. Compatible with PMU and standard tattoo pen machines. The Optima RL Long Taper series is the reference instrument for machine microblading procedures, hair stroke brows, and fine eyeliner, offering a level of precision and control that other brands cannot match. The Optima series is the absolute pinnacle of Kwadron engineering for micropigmentation — every needle passes through the strictest quality controls, the finish is achieved through multiple polishing stages with diamond pastes, and the taper geometry is microscopically verified for each batch. Premium packaging includes detailed traceability information and sterility certification. PMU technicians who invest in Optima are actually investing in their professional reputation — superior results on clients build a loyal client base and organic referrals.
Frequently Asked Questions What advantage does Long Taper offer over Medium Taper in PMU with RL? Long Taper has a more elongated point that penetrates skin more gradually and delicately. In PMU, where depths are very shallow (0.5-0.8mm for hair strokes), Long Taper offers maximum control — the line forms more precisely and controllably. Medium Taper penetrates more directly, which can be too aggressive on thin facial skin. Is Kwadron Optima RL Long Taper the best needle for hair strokes? Kwadron Optima RL Long Taper is considered one of the best needles for machine hair strokes on the market. The combination of polished 316L steel, Long Taper, and Kwadron manufacturing precision produces crisp, fine, and natural hair strokes. Many top PMU technicians consider it the reference standard for machine microblading. What RL Optima Long Taper configurations are available? Kwadron Optima RL Long Taper is available in fine configurations optimized for PMU: 1RL for ultra-fine hair strokes and single needle, 3RL for standard hair strokes and fine eyeliner, and 5RL for lip liner. 1RL is the most popular for elite hair strokes, 3RL is the most versatile for general PMU. How does Kwadron Optima RL compare to PMU Limited RL? The difference is significant. Kwadron Optima RL Long Taper has a significantly superior microscopic needle finish, Long Taper (vs. standard taper on Limited), and much tighter manufacturing tolerances. The result: finer, cleaner, and more natural hair strokes with less trauma. Optima is for elite PMU, Limited is for standard PMU. What voltage do you recommend for hair strokes with Kwadron Optima RL Long Taper? For hair strokes with Kwadron Optima RL Long Taper, we recommend very low voltage: 3.5-5V. Long Taper penetrates efficiently at low voltages, producing crisp hair strokes without excessive trauma. 1RL requires 3.5-4.5V, and 3RL requires 4-5V. Low voltage is key for fine, natural hair strokes. Excessive voltage causes thick lines and scarring. Is Kwadron Optima RL Long Taper good for permanent eyeliner too? Yes, Kwadron Optima RL Long Taper in 1RL or 3RL configuration is excellent for permanent eyeliner. The Long Taper allows ultra-precise lining on the extremely delicate skin around the eyes. Superior penetration control is essential in this area — wrong depth can cause pigment migration or ocular trauma. It is the premium choice for eyeliner. Why is 316L steel important for Kwadron Optima PMU needles?316L steel is medical grade — it has superior corrosion resistance, does not release nickel (a common allergen), and maintains sharpness longer than inferior steels. In PMU, where you work on the face and near mucous membranes, steel quality is critical. Kwadron's 316L steel is polished at microscopic level, reducing micro-imperfections that cause trauma and scarring. How much does a box of Kwadron Optima RL Long Taper cost? Kwadron Optima RL Long Taper has a premium price, reflecting the top quality of the range. The price per box is significantly higher than PMU Limited, but each cartridge offers superior performance and visibly better results. Check the current price on tatuat.ro — prices may vary depending on configuration and available promotions. Can Kwadron Optima RL Long Taper do hair strokes on oily skin? Oily skin is a challenge in PMU regardless of the needle used, but Kwadron Optima RL Long Taper offers the best chances of success. Long Taper allows controlled penetration even in oily skin where pigment tends to migrate. Reduce working speed, make multiple superficial passes, and use pigments with high retention for oily skin. How many Kwadron Optima RL cartridges do I need per eyebrow session? For a complete hair stroke brows session, plan for 2-3 Kwadron Optima RL Long Taper cartridges. Use one cartridge per eyebrow and always have one as backup. The superior Optima quality maintains sharpness longer than standard needles, but changing after each eyebrow ensures consistent, perfect hair strokes on both brows.
