STIGMA Tattoo Needle Cartridges 9RL Round Liner 50-Pack — Sterile Disposable with Anti-Backflow Membrane

These EN05-series cartridges were developed by tattooists for tattooists: each unit combines 304 surgical stainless steel needles with medical-grade plastic housings and an anti-backflow membrane, arriving individually E.O. sterilized in blister packaging. The 9RL configuration (nine needles in a tight round cluster) is tailored for crisp lining and fine detail when used with standard cartridge machines and compatible grips.

How do these cartridges protect my workflow and equipment?

The integrated rubber membrane blocks ink and fluid from flowing back into the machine, reducing contamination risk and cleaning time. Single-use, E.O. sterilized blister packs keep each cartridge ready-to-use straight from the box.

• Membrane barrier prevents backflow of ink and fluid
• E.O. sterilized individual blister packaging
• Single-use design eliminates cross-contamination between clients
• Compatible with most standard cartridge tattoo machines and grips

What performance can I expect from the 9RL configuration?

The 9RL (nine round-liner) grouping provides a concentrated point for clean, consistent lines and smooth dot work. It's ideal for outlining medium-to-large strokes and adding defined detail without excessive skin trauma when used with correct technique.

• Nine tightly grouped needles for bold, uniform lines
• Slope-designed round tips for controlled ink flow
• Suitable for outlines, lettering, and dot-shading accents
• Stainless steel needles maintain shape and sharpness session-to-session

Are these cartridges durable and compatible with my equipment?

Constructed from 304 surgical stainless steel and medical-grade plastic, the cartridges are robust and dimensioned to fit standard cartridge systems. The connection geometry and depth are carefully designed for stable seating and predictable needle movement.

• 304 surgical stainless steel needles resist bending and corrosion
• Medical-grade plastic housing for secure fitment
• Works with most cartridge-style tattoo machines and grips
• Consistent factory assembly for repeatable performance

Who is this for: Tattoo professionals and serious apprentices who want reliable, sterilized round-liner cartridges in bulk. The 50-piece pack suits busy studios, guest artists, and anyone who values consistent lining performance and the protection of an anti-backflow membrane. These cartridges are intended for single use by trained tattoo artists and should be disposed of following local biohazard regulations.
