STIGMA Tattoo Needle Cartridges 9RL Round Liner 50-Pack — E.O. Sterile, Membrane Safety for Crisp Lines

STIGMA #12 (9RL) disposable round liner tattoo cartridges are sterilized, membrane-protected needle units made from 304 surgical stainless steel and medical-grade plastic for consistent, hygienic line work.

These EN05-series cartridges come in a super value pack of 50, engineered by tattoo artists to fit standard cartridge machines and grips. Each cartridge is E.O. sterilized and sealed in a blister pack with an integrated rubber membrane to reduce backflow, helping keep your tubes and machines cleaner between uses. The round liner configuration with a tapered profile is built to provide precise, controlled lines for fine detailing and lettering.

How do these cartridges help me achieve cleaner line work?

The 9RL grouping concentrates nine needles into a compact round tip with a slight taper, giving smooth ink flow and sharper edges for outlines and intricate details. The needle geometry minimizes splaying while the stainless construction maintains consistent rigidity.

• 9-needle round liner for tight, crisp outlines
• Tapered tips reduce skin trauma and skipping
• 304 surgical stainless steel for uniform needle strength
• Pre-mounted in cartridges for steady alignment and control

Are these cartridges safe and ready to use straight from the pack?

Yes — each cartridge is E.O. sterilized and individually blister-sealed to preserve sterility until opened. A built-in rubber membrane helps block ink and fluid from traveling back into the grip and machine, improving hygiene during busy sessions.

• Ethylene oxide (E.O.) sterilization ensures clinical-level processing
• Blister packaging keeps individual units sterile until use
• Membrane barrier reduces ink backflow into tubes and machines
• Single-use design eliminates reprocessing and cross-contamination risks

Will these cartridges fit my existing equipment and work with different styles?

The EN05 series is designed for compatibility with most standard cartridge-ready tattoo machines and grips, allowing quick swaps mid-session and comfortable handling. Their round liner format is versatile for lining, small script, and detailed dotwork.

• Compatible with standard cartridge tattoo machines and grips
• Quick-change fit for efficient workflow
• Suitable for outlines, fine detail, and shading accents
• Medical-grade plastic housing for reliable seating and release

How do these cartridges help me manage hygiene and studio efficiency?

Pre-sterilized, disposable cartridges eliminate the need for manual needle handling and sterilization, saving time and reducing contamination risk. The membrane safety feature minimizes fluid transfer, which helps preserve machine cleanliness and reduces post-session cleaning.

• Single-use cartridges speed up turnover between clients
• Membrane protects internal components from ink and bloodback
• Individually sealed to maintain sterility until required
• Pack of 50 offers better stocking and cost efficiency for busy artists
