Complete guide: CARTRIDGE TATTOO NEEDLES LIMITED M1
LIMITED M1 cartridges are tattoo needles in flat magnum configuration: the needles are arranged in two parallel rows, in a wide formation, designed for dense color packing and uniform fills on large surfaces. They are made of stainless steel, have an anti-backflow safety membrane, and come sterilized with ethylene oxide, in individual blister packs with sterility indicator. They are suitable both for artists working with solid color styles (Traditional, Neo-Traditional, New School, Japanese) and for high-volume studios, due to the LIMITED series' price-quality ratio.
How to use
- Check the blister before opening: it must be intact, sealed, and with the sterility indicator present. A damaged blister means you do not use the cartridge.
- Prepare the work station hygienically: disposable gloves, sanitized pen covered with a protective barrier (sleeve/foil), protected surfaces.
- Open the sterile blister without touching the needle tips and insert the cartridge into the pen grip until it clicks into place — the connection is standard cartridge fit.
- Adjust the needle projection from the grip and set the power supply: for color packing with M1, the manufacturer recommends a range of 8–11V as a starting point, adjusted according to the pen, ink, and skin type.
- Start at the lower end of the voltage range and increase gradually until you achieve the desired saturation, checking the needle stroke before working on skin.
- Work with small circular or slow pendulum motions, slightly overlapping each pass — the flat formation of the M1 covers wide and distributes ink densely and evenly.
- At the end, remove the cartridge and discard it immediately in the sharps container. The cartridge is a single-use consumable.
- Sanitize the pen and replace all protective barriers before the next client.
Tips from us
- Choose the configuration according to the work surface: the range goes from 7M1 to 23M1 — 9M1/11M1 for medium areas, 13M1/15M1 for large surfaces, 17M1–23M1 for backgrounds and quick fills on extensive areas.
- Use M1 where you want full saturation and solid colors; for soft transitions and gradual shading, a Round Magnum (RM) remains the more suitable choice.
- Do not compensate by pressing: the flat magnum already covers a wide band with each pass — let the light overlaps build saturation, not pressure.
- The anti-backflow membrane prevents cross-contamination to the pen, but does not replace the protective barriers on the machine and grip — always use them together.
- Test the new configuration on practice synthetic skin before using it on a client, to calibrate your voltage and hand speed for that width.
Warning: Tattoo needles are strictly single-use devices: never resterilize or reuse a cartridge, not even for the same client in a later session. Do not use cartridges with opened, damaged blisters, or without a sterility indicator. Always work with gloves and protective barriers, and after use, immediately discard the cartridge in the special sharps container, according to sanitary regulations for tattoo studios.
Frequently asked questions
What does the M1 configuration mean and how is it different from RM?▾
M1 (Magnum) has needles arranged flat, in two parallel rows, creating a wide and uniform contact surface — it distributes ink densely and aggressively, ideal for color packing and full saturation. RM (Round Magnum) has needles curved in a fan shape and offers softer transitions, suitable for gradual shading and blending. In short: M1 for saturation, RM for transitions.
Are the LIMITED M1 cartridges compatible with my pen?▾
Yes — the cartridges have a standard cartridge fit and are universally compatible with pens that accept this system. The manufacturer confirms operation with pens such as Cheyenne, FK Irons, Bishop, Kwadron Proton, InkJecta, or Dragonhawk. If your pen uses standard cartridges from any other brand, LIMITED M1 will fit identically.
What size of M1 do I choose depending on the work?▾
The LIMITED M1 range covers configurations from 7M1 to 23M1. For medium areas, the most used are 9M1 and 11M1; for large surfaces, 13M1 and 15M1; and for backgrounds and very extensive fills, 17M1 to 23M1. The practical rule: the larger the area to fill, the wider configuration you choose, to reduce the number of passes.
Can I reuse a cartridge if I work on the same client in two sessions?▾
No. The cartridges are sterile single-use — the ethylene oxide sterilization and individual blister guarantee safety only until first opening. Once used, the cartridge is discarded in the sharps container, regardless of whether it's the same client. Reusing or 're-sterilizing' at home is a real risk of infection and a violation of hygiene standards.
Can I also use LIMITED M1 for shading?▾
Yes, but with different results compared to RM or RS: M1 produces dense and even shading, suitable for block shading or stepped gradients. It is not the ideal choice for delicate, portrait-type transitions — there an RM provides much finer transitions. If the work requires both, many artists combine M1 for fills with RM for transition areas.
At what voltage do I work with LIMITED M1 on color packing?▾
The manufacturer's recommendation for color packing is the range 8–11V: start at 8V and increase gradually until you achieve the desired saturation. The optimal voltage depends on the pen used, ink viscosity, and skin type, so calibrate it for each setup — ideally first on practice skin.
Product description
Limited M1 (Magnum) cartridge needles are professional tattoo needles with a flat magnum configuration, designed for dense color packing and uniform fills across large areas. The needles are arranged in two parallel rows in a flat formation, providing maximum coverage per pass. Manufactured from high-quality stainless steel with a polished finish, these Limited M1 cartridges integrate an anti-backflow safety membrane for cross-contamination prevention. The M1 configuration is the fundamental instrument for any artist working with solid colors — Traditional, Neo-Traditional, New School, and Japanese styles. Unlike Round Magnum (RM), the flat M1 distributes ink more aggressively and uniformly, ideal for complete saturation without uncovered patches. Ethylene oxide sterilization and individual blister packaging guarantee safety. Universally compatible with all standard cartridge-grip tattoo pen machines. The Limited series offers an exceptional quality-to-price ratio, making these cartridges accessible to both high-volume studios and independent artists who want consistent performance without the premium cost of top-tier ranges. Available in configurations from 7M1 to 23M1. The Limited series is manufactured with the same commitment to safety as premium ranges — every cartridge undergoes EO gas sterilization, has a tested safety membrane, and is packaged in a blister with sterility indicator. The price difference from premium ranges reflects a simplified finishing process, not compromises in safety or base materials. Artists transitioning from no-name cartridges to Limited immediately notice the difference in performance consistency and the healing quality of completed tattoos.
Frequently Asked Questions What is the M1 configuration and how does it differ from RM? M1 (Magnum) has needles arranged flat in two parallel rows, creating a wide, uniform contact surface. RM (Round Magnum) has needles curved in a fan. M1 distributes ink more aggressively and densely, ideal for color packing. RM offers softer transitions, ideal for gradual shading. M1 is for saturation, RM is for blending. What tattoo styles are best suited for Limited M1? Limited M1 excels in styles requiring solid colors and complete saturation: Traditional American with dense color blocks, Neo-Traditional with gradient and saturation, Japanese with backgrounds and clouds, New School with vibrant colors. It is also excellent for solid blackwork and tribal with uniform fills. What is the advantage of the Limited series over other premium ranges? The Limited series offers an exceptional quality-to-price ratio. These cartridges have the same basic construction — quality steel, safety membrane, EO gas sterilization — but at a more accessible price than premium ranges like Kwadron or Cheyenne. Differences are minor and only visible at micro-finish level, making Limited ideal for practice and high volume. What voltage do you recommend for Limited M1 on color packing? For color packing with Limited M1, we recommend voltage between 8-11V. The flat magnum configuration requires sufficient power to distribute ink uniformly across the full needle width. Start at 8V and increase until you achieve desired saturation. Optimal voltage depends on the pen used, skin type, and ink viscosity. How many needles do the available Limited M1 configurations contain? Limited M1 is available in configurations from 7M1 (7 needles in two rows) to 23M1 (23 needles). The most popular are: 9M1 and 11M1 for medium areas, 13M1 and 15M1 for large surfaces, and 17M1-23M1 for rapid background fills or very extensive areas. Choose the configuration based on the size of the work area. Can Limited M1 be used for shading as well? Yes, Limited M1 can be used for shading, but with different results than RM or RS. M1 produces denser, more uniform shading without soft gradual transitions. It is suitable for block shading or stepped gradients, but not for delicate portrait-type transitions. For fine shading, prefer the RM. How does Limited M1 quality compare to Kwadron M1? Kwadron M1 has a finer microscopic finish with tighter manufacturing tolerances. Limited M1 offers very good performance at a more accessible price. For top-tier work on premium clients, Kwadron is the superior choice. For practice, high-volume sessions, or students, Limited M1 offers excellent value without major compromises. Is Limited M1 compatible with my tattoo pen? Yes, Limited M1 cartridges are universally compatible with all tattoo pens that accept standard cartridges. They work with Cheyenne, FK Irons, Bishop, Kwadron Proton, InkJecta, Dragonhawk, and any other pen with a standard cartridge grip. The attachment is identical to any other professional cartridge on the market. What movement technique do I use with Limited M1 for color packing? For color packing with Limited M1, use small circular motions or slow pendulum movements, slightly overlapping each pass over the previous one. Maintain a constant 45-90 degree angle and uniform pressure. Work systematically — area by area — to ensure complete saturation without leaving gaps or overworking already saturated zones. How many Limited M1 cartridges do I need for an average session? For an average color packing session (2-4 hours), plan for 2-4 Limited M1 cartridges per main color. An M1 cartridge maintains good performance for 1-2 hours of continuous color packing. Change the cartridge when you notice saturation decreasing or ink not distributing evenly. Always have spare cartridges ready.
