HAWINK Tattoo Needle Cartridge Kit 50pcs — Assorted Round Liners & #10 Bugpin, Sterile Membrane, Universal Fit

HAWINK 50PCS Tattoo Needle Cartridge Assorted Mixed Size Round Liner kit is a sterile, disposable set of precision stainless-steel cartridges designed for consistent, smooth lining and reliable ink flow across standard tattoo machines.

This professional cartridge pack brings together multiple round liner sizes plus bugpin options to cover detailed work and general lining in one box. Each cartridge is manufactured from 304L stainless components, finished with a black transparent hard silicone handle and a full membrane to minimize ink backflow. The RGB color-coding helps you spot RL/RS and RM types at a glance for faster setup during busy sessions.

What needle sizes are included and when would I use each?

The kit contains a variety of round liner sizes—3RL, 5RL, 7RL, 9RL, 11RL—and #10 bugpin. Smaller RL sizes and the bugpin are ideal for tight details and crisp single-pass lines, while larger RLs suit bold outlines and faster coverage. This mix lets you switch quickly between fine work and stronger outlines without changing cartridge types.

• 3RL & bugpin: fine lines, script, microdetails
• 5RL & 7RL: medium lines, delicate contours
• 9RL & 11RL: thicker outlines, faster stroke fills

How does the cartridge design protect my equipment and improve workflow?

Each HAWINK cartridge uses a full silicone membrane that prevents ink from traveling back into the machine, reducing contamination risk and maintenance. The hard silicone handle gives a stable, non-slip grip which improves control on long sessions. Two-color coding aids quick selection so you stay efficient during appointments.

• Full membrane: guards against ink backflow and motor contamination
• Black transparent hard silicone handle: improved grip and durability
• Yellow-green / grape color code: fast visual identification

Are these cartridges compatible with my tattoo machine and are they sterile out of the box?

HAWINK cartridges are made to fit all standard cartridge-style rotary and coil machines as well as Hawk machines and grips, making them widely compatible in most professional setups. Each cartridge is EO gas sterilized, delivered in sealed packaging so you can use them straight from the box with confidence in their sterile state.

• Universal fit: works with most rotary and coil cartridge systems
• 100% EO gas sterilized: ready for safe professional use
• Box of 50: convenient supply for multiple sessions

How do these cartridges affect needle performance and consistency?

Precision manufacturing from 304L stainless steel ensures consistent needle alignment and sharpness for predictable line quality. The mixture of sizes and the inclusion of bugpin provide flexibility without sacrificing stability, while the cartridges’ build reduces wobble and improves ink delivery for cleaner strokes.

• 304L stainless steel needles: durable, sharp, corrosion-resistant
• Consistent manufacturing: uniform needle grouping and alignment
• Assorted pack: ready for varied tattoo styles and techniques
