STIGMA Tattoo Cartridges 3RL Bugpin Round Liner — 50pcs Pack, Sterile Membrane Safety for Fine Lining

STIGMA #10 (3RL) Bugpin disposable tattoo cartridges are sterile, membrane-protected round-liner needles engineered for precise lining and fine detail work.

Designed by tattoo artists for tattoo artists, these EN05-series cartridges combine surgical-grade materials, a backflow-preventing membrane and a bugpin 3RL configuration to deliver consistent, reliable performance during sessions. Each cartridge is E.O. sterilized and supplied in blister packaging, ready for immediate use with most cartridge-compatible rotary or pen-style machines and grips.

How does the 3RL bugpin configuration improve lining and small details?

The 3RL (three round liner) bugpin arrangement uses smaller-diameter needles packed tightly to create cleaner, crisper lines with less trauma to the skin. This configuration is ideal for hairlines, micro-lines and artwork that demands fine precision.

• Tighter needle grouping for higher line definition
• Reduced ink spread and blowouts on thin skin
• Better control at lower machine speeds for delicate work

What safety features protect against contamination and backflow?

Each STIGMA cartridge includes an integrated rubber membrane that prevents ink and blood from traveling back into the machine or tube, reducing cross-contamination risk. The cartridges are individually E.O. sterilized and blister-sealed to preserve sterility until opened.

• Medical-grade plastic housing with sealed membrane
• E.O. sterilization validated for single use
• Blister packaging to maintain sterile integrity

Will these cartridges fit my tattoo machine and how easy are they to load?

STIGMA EN05 cartridges are built to the common cartridge standard and are compatible with most cartridge-style rotary and pen machines and ergonomically designed grips. The snap-fit design lets artists install or replace cartridges quickly during sessions.

• Standard cartridge connection works with major machine brands
• Ergonomic shape for secure grip and precise handling
• Quick-swap compatibility for efficient workflow

What materials and sterilization methods are used in these disposable cartridges?

The needles are made from 304-grade surgical stainless steel and the cartridge bodies use medical-grade plastics chosen for strength and biocompatibility. Ethylene oxide (E.O.) gas sterilization ensures each blister-packed unit reaches the artist sterile and safe for single-use procedures.

• 304 surgical stainless steel needles for corrosion resistance
• Medical-grade plastic housing and rubber septum
• E.O. sterilized then blister-sealed for one-time use

This 50-piece value pack is suitable for busy studios that perform detailed lining, micro-realism touches and precision work, and for artists who use cartridge-compatible machines and grips and want sterilized, ready-to-use disposables on hand.
