STIGMA Tattoo Needle Cartridges 9RL Bugpin 50pc Pack — Disposable Membrane Safety Round Liner

STIGMA #10 (9RL) Bugpin disposable needle cartridges are sterilized, membrane-protected 9-round-liner cartridges sold in a 50-piece pack for precise, hygienic tattoo lining.

This super-value pack of STIGMA EN05-50-1009RL cartridges pairs ultra-fine bugpin rounds with a one-way membrane to help prevent ink backflow while fitting most cartridge-style tattoo machines. Designed by tattoo artists, these single-use assemblies combine surgical-grade stainless steel needles with medical-grade plastic housings and come E.O. sterilized in blister packaging so you can open a fresh cartridge for every client or session.

How do these cartridges improve line work?

The 9RL bugpin configuration delivers tighter, denser lines than standard round liners, giving you more control for crisp outlines and fine details. The slightly sloped needle tips help penetrate smoothly while maintaining ink flow consistency, which is especially useful on intricate designs.

• 9-round bugpin cluster for fine, controlled lines
• Slope-shaped tips for even skin contact
• Consistent ink delivery for clean outlines

Are these cartridges compatible with my machine and grips?

STIGMA EN05 cartridges are made to fit standard cartridge-compatible rotary and coil machines and most cartridge grips on the market. The universal hub and rubber band loading make installation quick, and the plastic shell keeps the needle stable during use.

• Standard cartridge hub fits most machines and grips
• Rubber band preload reduces needle play
• Compact shell for secure attachment and balance

What safety and sterilization features are included?

Each cartridge is E.O. (ethylene oxide) sterilized and sealed inside a blister pack to ensure sterility until opening. The integrated membrane stops ink and fluid from migrating back into the grip or machine, helping maintain a cleaner workspace and lowering contamination risk.

• E.O. sterilized individual blister packaging
• One-way plastic membrane prevents ink backflow
• Disposable single-use design for infection-control protocols

What construction and materials are used in these cartridges?

The needles are manufactured from 304 surgical stainless steel for corrosion resistance, while the housings use medical-grade plastic to ensure durability and safe handling. The combination creates a lightweight, reliable cartridge intended for daily professional use.

• 304 surgical stainless steel needles for durability
• Medical-grade plastic housing for safe handling
• Designed by tattoo artists to meet studio workflows

Who is this for? The STIGMA #10 (9RL) Bugpin disposable cartridges suit professional tattoo artists and apprentices who need a high-volume, reliable supply of fine round liners with safety features. If you focus on detailed linework, micro-details, or require strict single-use protocols in a busy studio, this 50-pack offers value, consistency, and the convenience of membrane-protected cartridges.
