HAWINK 7RL Bugpin Tattoo Needle Cartridges — 50 pcs, X-Taper 7 Round Liner with Anti-Backflow Membrane

HAWINK 7RL Bugpin Tattoo Needle Cartridges are sterile, single-use 7-round liner cartridges with X-taper bugpin needles, supplied in a 50-piece box and fitted with anti-backflow membranes.

These cartridges are engineered for precise lining work, combining fine bugpin tips with an X-taper profile to deliver controlled ink flow and sharp, consistent lines. Each cartridge is individually EO gas sterilized and constructed using medical-grade materials for the needle tip and durable plastics for the housing. They’re compatible with most rotary and coil machines and include silicone components that stabilize needle action for smoother performance.

How do these cartridges improve line work?

The 7-round bugpin configuration creates tighter, more compact groupings compared with standard liners, which helps achieve finer, crisper lines and detailed work. The X-taper design refines ink delivery so the needle carries pigment consistently without sudden splatters.

• Bugpin 7RL grouping for dense, sharp lines
• X-taper profile for balanced ink flow
• Fine tip geometry reduces skin trauma during tight lining
• Semi-transparent tip helps monitor needle strike and ink pickup

Are these safe and ready to use straight from the pack?

Yes — every cartridge is sealed and sterilized with EO gas, then packaged individually for single-use convenience. A built-in membrane prevents ink and fluid backflow into the grip or machine, reducing contamination risk during procedures.

• 100% EO gas sterilized and individually wrapped
• Integrated membrane to block ink backflow
• Medical-grade 316 stainless steel needle tips
• Disposable design eliminates the need for reprocessing

Which machines and grips will these fit?

These HAWINK cartridges are designed to be broadly compatible with most cartridge-ready rotary and coil machines, including HAWINK systems and standard cartridge grips. The universal connection and compact housing make swapping quick and tool-free for most setups.

• Fits all standard cartridge-compatible rotary and coil machines
• Works with HAWINK machine models and common grips
• Easy snap-in connection for rapid cartridge changes
• Consistent seating prevents wobble during use

What materials and build details matter for longevity and performance?

The needle tips are 316 medical-grade stainless steel for corrosion resistance and sharpness retention, while the cartridge body uses durable medical-grade plastic. High-quality silicone components help maintain needle elasticity and smooth recoil, contributing to consistent strikes and reduced vibration.

• 316 stainless steel needle tips for durability
• 304 stainless steel elements used where appropriate
• Medical-grade plastic housing for structural stability
• Quality silicone bushings for needle elasticity and smoother action
