STIGMA Tattoo Cartridges 3RL Round Liner 50-Pack — Sterile Disposable Cartridges with Anti-Backflow Membrane

These STIGMA EN05 series cartridges combine surgical-grade stainless steel needles with medical-grade plastic bodies and an anti-backflow membrane, offering a ready-to-use option for tattoo artists who prioritize hygiene, control, and compatibility. Each cartridge arrives E.O. sterilized in blister packaging and fits standard cartridge machines and grips, making them a straightforward replacement for daily studio use.

How do these cartridges control ink backflow and contamination?

The cartridges include an integrated rubber band and a plastic membrane barrier that prevents ink and bodily fluids from traveling back into the tube during use. This mechanical separation reduces the chance of cross-contamination while keeping the machine cleaner and safer between clients.

• Membrane barrier prevents ink from flowing back into the tube
• Rubber band loading increases cartridge stability during operation
• E.O. sterilized, individually blister-packed for single-use hygiene

What needle construction and materials are used for line work?

The needles are manufactured from 304 surgical stainless steel and shaped specifically for round-liner tasks. The round tip geometry and precise slope support consistent line placement and crisp detailing with each stroke.

• 304 surgical stainless steel needles for durability and corrosion resistance
• Round-liner 3RL configuration suited to fine and medium lines
• Needles formed with a slope tip for controlled ink deposition
