STIGMA Tattoo Needle Cartridges 7RL Round Liner 50-Pack — Sterile Membrane, 304 Surgical Steel Precision

STIGMA #12 (7RL) are single-use round-liner tattoo cartridges with a protective membrane, sterilized and ready for professional use.

These STIGMA EN05-50-1207RL cartridges come in a 50-count super value pack engineered for repeatable precision and safe ink flow control. Each cartridge combines 304 surgical stainless steel needles with medical-grade plastic housing and a one-way membrane to reduce backflow. E.O. sterilized and individually blister-packed, they are built to fit standard cartridge-style tattoo machines and grips for straightforward integration into studio workflows.

How do these cartridges help me maintain a cleaner workflow?

The built-in rubber-loaded membrane limits ink and fluid travel back into the machine, lowering the risk of cross-contamination and reducing cleanup time. Individual blister sterilization also preserves sterility until you’re ready to use, keeping the studio environment controlled.

• One-way membrane minimizes ink/backflow into tubes
• Individually E.O. sterilized blister packs
• Disposable single-use design for simple, hygienic disposal
• Medical-grade materials easy to wipe down between clients

What kind of lines and detail can I achieve with the 7RL configuration?

The 7RL (seven-round liner) groups seven needles in a tight round formation, delivering crisp, consistent outlines and fine detail work when used with the right machine settings and hand speed. The needle tips are shaped for controlled penetration and dependable ink delivery.

• Tight round grouping for sharp, consistent lines
• Needle tip geometry optimized for detail and crisp borders
• Best for outlining, fine detail, and small script work
