STIGMA #12 (5RL) are sterile, disposable round-liner tattoo needle cartridges with a protective membrane, sold in a 50-piece pack for reliable linework and contamination control.

These EN05 series cartridges were developed by tattoo artists for tattoo artists, combining surgical-grade materials with a sealed membrane to reduce ink backflow. Each cartridge is E.O. sterilized and shipped in individual blister packaging, giving studios a ready-to-use option for crisp lines and safer setup. The pack contains fifty 5RL (5-round liner) cartridges compatible with most standard cartridge machines and grips.

How do these cartridges help me keep a clean workstation?

The sealed plastic membrane on each STIGMA cartridge prevents ink and fluid from flowing back into the machine, lowering cross-contamination risks during sessions. Individual blister packs maintain sterilization until opened, making disposables simple to handle and replace between clients.

• Membrane barrier reduces ink backflow to tubes and motors.
• E.O. sterilized cartridges in individual blister packs.
• Disposable single-use design eliminates sterilization between clients.
• Fits standard cartridge grips for quick swaps mid-session.

What needle construction and materials are used?

STIGMA cartridges use 304 surgical stainless steel needles and medical-grade plastic housings to ensure consistent strength, corrosion resistance, and smooth ink flow. Needles are precision-formed for round-liner work, with slopes optimized for clean, consistent lines and controlled ink delivery.

• 304 surgical stainless steel needles resist rust and wear.
• Medical-grade plastic cartridges for durability and safety.
• Needle geometry tailored for tight, even lines and detail.
• Rubber band loading supports stable needle movement.

Will these cartridges fit my equipment and what work are they best for?

• Standard cartridge connection fits wide range of machines.
• 5-round liner configuration for bold or precise linework.
• Works well for lettering, fine details, and outlining.
• Easy mid-session changeover without re-sterilizing equipment.

How are these cartridges packaged and what safety certifications do they have?

• E.O. (ethylene oxide) sterilization for single-use safety.
• Blister pack keeps each cartridge sterile and traceable.
• Plastic membrane prevents fluid ingress and backflow.
