HAWINK Tattoo Needle Cartridge Kit 50PCS Assorted Sizes — Full Membrane, Black Silicone Handle, EO Sterile

HAWINK 50PCS Tattoo Needle Cartridge Kit delivers a complete assortment of round liners, round shaders and magnums with universal fit, membrane protection and ergonomic black hard-silicone handles for reliable tattoo work. This kit gives artists a ready-to-use selection of precision-formed cartridges in popular sizes so you can switch between lining, shading and packing without changing tools. Each cartridge is manufactured from 304L stainless steel, EO gas-sterilized, and color-coded for quick identification. The full membrane design prevents ink backflow and protects your machine, while the rigid black transparent silicone handle improves grip and control during long sessions.

What sizes are included and why does that matter?

The set contains 50 cartridges: 5 pieces each of 3RL, 5RL, 7RL, 3RS, 5RS, 7RM, 9RM, 11RM, 13RM and 15RM. This mix covers fine lining, mid-size liners, tight shaders and a range of magnums for packing and soft shading. Having this spectrum on hand speeds workflow and reduces the need to reorder frequently.

• 3RL–7RL: precise lines, fine detail work
• 3RS–5RS: short mag-style rounds for small shading
• 7RM–15RM: flat and curved mags for color packing and gradients
• 5 pieces of each size to ensure consistency across sessions

How does the membrane and handle improve safety and performance?

The integrated full membrane prevents ink and fluid backflow into your machine, reducing contamination risk and prolonging motor life. The cartridges are EO gas-sterilized for single-use safety right out of the box. The hard, black transparent silicone handle offers a non-slip grip and greater durability than softer caps, giving steadier hand control.

• Full membrane: blocks ink backflow and protects machines
• EO gas sterilization: sterile upon opening for safe single use
• Hard silicone handle: improved grip and longer lifespan
