The design prioritizes ink pickup, smooth retraction and visibility so you can focus on precision work.

How do these cartridges improve line work for tattooing?

The 3 round liner configuration concentrates three needles into a tight cluster for crisp, controlled lines. The needle edges are shaped to capture and hold more ink at the tip, reducing the need for repeated passes and helping maintain steady line density.

• 3RL grouping for fine-to-medium lines with consistent ink flow
• Needle edges engineered to increase ink pickup
• Transparent housing for clear visual of ink and needle action

Are these cartridges safe and compatible with my machine?

Each cartridge is made from medical-grade PVC and high-quality stainless steel, assembled in a controlled environment and sealed individually to maintain sterility until use. The cartridges follow a standard size that fits most cartridge grips and pen-style machines, allowing quick twist-and-lock installation.

• Individually sealed packaging to preserve cleanliness
• Anti-backflow soft-glue parts to protect motors and clients from contamination
• Standardized connector works with common cartridge grips and pen machines

What performance features do these cartridges offer during sessions?
