HAWINK Tattoo Needle Cartridge Kit 50PCS — Assorted Sizes with EO-Sterilized Full Membrane

HAWINK 50PCS Tattoo Needle Cartridge Kit delivers a sterilized, mixed-size assortment of round liners, round shaders, magnums and curved magnums with anti-backflow membranes and a hard silicone grip for professional tattoo work.

This kit supplies 50 ready-to-use cartridge needles in an organized, color-coded set designed for both rotary and coil machines. Built from 304L stainless steel and EO gas sterilized, each cartridge is fitted with HAWINK's transparent hard silicone handle and a full membrane to reduce ink backflow. The assortment covers small liners through larger magnums, helping artists switch between precise lining, smooth shading and packing color without swapping needle systems.

What needle sizes are included and how are they arranged?

The pack contains ten sets of five different cartridges for a total of 50 pieces: 3RL, 5RL, 7RL (round liners), 3RS, 5RS (round shaders), and 7RM, 9RM, 11RM, 13RM, 15RM (round/curved magnums and magnums). That spread gives you fine liners, mid-size shaders and multiple magnum options for color packing and soft gradients.

• 5× 3RL, 5× 5RL, 5× 7RL for crisp, controlled lines
• 5× 3RS, 5× 5RS for detailed shading and soft blends
• 5× each of 7RM, 9RM, 11RM, 13RM, 15RM for efficient color packing and smooth gradients

How does the cartridge construction protect my machine and improve workflow?

Each cartridge features a full internal membrane that prevents ink and fluid from entering the machine, lowering contamination risk and protecting internal components. The membrane also yields more consistent ink flow and fewer interruptions during sessions.

• Full membrane design for backflow protection
• Black transparent hard silicone handle for a secure, ergonomic grip
• Universal fit for most rotary and coil tattoo machines and grips

Are these cartridges safe and ready to use straight from the box?

Yes — the needles are made from corrosion-resistant 304L stainless steel and are sterilized using 100% EO gas, meeting professional hygiene expectations. Individual packaging and sterilization minimize cross-contamination risks and let you deploy cartridges immediately when you open the box.

• 304L stainless steel for strength and consistent performance
• 100% EO gas sterilized for clinical-level decontamination
• Sealed packaging to preserve sterility until use

How does color coding and compatibility speed up sessions?

HAWINK uses a two-color system that separates liner/shader cartridges from magnums at a glance: yellow-green indicates RL/RS, while grape signals RM magnums. This visual cue reduces selection time, and the universal connection fits most cartridge machines so you won’t need adapter swaps mid-session.

• Two-color coding for immediate needle-type recognition
• Universal cartridge connection fits most machines and grips
• Boxed set keeps inventory organized for fast access

Who is this for? The HAWINK 50PCS cartridge kit is aimed at professional and aspiring tattoo artists who want a broad, ready-to-use variety of liners, shaders and magnums in one sterilized pack. It’s useful for shop environments, guest spots, apprentices practicing technique, and artists who need dependable, easy-to-grip cartridges that protect their equipment and speed up session flow.
