HAWINK Tattoo Cartridges 50pc Mixed Round Liner Set 3RL–11RL — EO-Sterile, Leak-Resistant

HAWINK Tattoo Cartridges 50pcs Mixed Round Liner set delivers a sterile, mixed-size pack of 3RL–11RL needle cartridges for precision lining and consistent ink flow.

These HAWINK EN05S-50KIT-E cartridges combine medical-grade materials, leak-resistant membranes, and compatibility with most rotary and coil machines to streamline tattoo sessions. Individually EO-sterilized and packed, the kit includes a variety of standard round liner sizes designed for everything from fine hairlines to bold outlines. The semi-transparent housing makes needle movement visible, while silicone components maintain smooth needle return and feel.

What sizes are included and when would I use each?

The kit contains mixed standard round liner sizes: 3RL, 5RL, 7RL, 9RL and 11RL — a practical range for common lining tasks. Smaller counts (3RL, 5RL) are great for delicate, detailed lines; medium sizes (7RL, 9RL) handle general outlines and shading edges; 11RL suits bold outlines and larger solid lines.

• 3RL — fine detail, micro-lines, script finishing
• 5RL — crisp outlines, small lettering
• 7RL — standard outlines, medium details
• 9RL — thicker lines and small blackwork areas
• 11RL — bold outlines and heavy linework

How do these cartridges prevent leaks and keep ink consistent?

Each cartridge includes an internal membrane that blocks ink backflow into the machine, and the bevel tip design allows clear visibility of the needle strike for controlled ink delivery. The semi-transparent housing and secure fit reduce splash and help you monitor saturation without interrupting workflow.

• Membrane barrier prevents ink migration to the tube or motor
• Bevel tip improves line visibility and needle placement
• Semi-transparent body lets you watch needle motion and ink flow
• Secure seal minimizes splatter and contamination risk

What materials and sterilization standards are used?

HAWINK cartridges use 316 stainless steel for needle tips and 304 stainless steel elsewhere, paired with medical-grade plastic bodies and high-quality silicone for elastic needle return. Each cartridge is EO gas sterilized and individually packaged to maintain sterility until use.

• 316 stainless steel needle tips for corrosion resistance
• 304 stainless components for structural strength
• High-grade silicone for smooth needle rebound
• 100% EO gas sterilized and single-use packaging

Are these cartridges compatible with my tattoo machine?

• Compatible with most rotary machines
• Works with coil machines that accept cartridge-style needles
