STIGMA Bugpin Tattoo Needle Cartridges 7RL — 50-Pack Disposable Sterile Cartridges for Precise Round Liner Work

STIGMA #10 (7RL) Bugpin disposable cartridges are sterile, membrane-sealed round-liner needle cartridges designed for precise, comfortable lining and detail work for professional tattoo artists.

These EN05-series cartridges pair surgical-grade stainless steel needles with medical-grade plastic housings and a one-way membrane to help prevent ink backflow. Supplied E.O. sterilized in blister packaging, the pack contains 50 ready-to-use 7RL (7 round liner) bugpin cartridges that fit most standard cartridge tattoo machines and grips. They emphasize fine-point control for crisp lines, controlled ink flow, and easy handling during long sessions.

How do these cartridges support precise lining and detail?

The bugpin configuration uses finer needle tips stacked to form a tight 7-needle cluster, giving a sharper point and improved edge retention compared with standard RL configurations. This makes them well suited for hairlines, micro-lines, and intricate outlines where clean edges matter.

• 7RL bugpin layout delivers a finer, tighter point for crisp lines.
• Stainless steel needles reduce flex for consistent stroke results.
• Flat-to-slope needle shaping helps maintain ink pickup and transfer.
• Standard cartridge fit for wide machine and grip compatibility.

What safety and hygiene features are included?

Each cartridge is E.O. sterilized and individually sealed in a blister pack, ensuring sterile condition until opening. The built-in rubber membrane minimizes ink and blood draw-back into the machine tube, improving client safety and simplifying cleanup.

• Ethylene oxide sterilization for single-use sterility assurance.
• Membrane barrier prevents backflow into the grip and machine.
• Medical-grade plastic housing reduces breakage risk during sessions.
• Disposable design eliminates the need for needle reprocessing.

Are these cartridges compatible with my tattoo setup?

STIGMA EN05 cartridges follow standard cartridge dimensions and will work with the majority of cartridge-style machines and grips on the market. Their universal fit makes them an easy option to integrate into an existing kit without adapters or workflow changes.

• Fits common cartridge rotary and coil machines with cartridge grips.
• No special adapters required for most setups.
• Consistent hub design for secure seating and minimal wobble.
• Available in multiple configurations within the EN05 series for matching other needle types.

How should I use and store these cartridges for best results?

Use each cartridge straight from its sterile blister pack and discard after one client or procedure. Store unopened cartridges in a cool, dry place away from direct sunlight and inspect the seal before use to confirm sterility.

• Open the blister only when ready to tattoo to preserve sterility.
• Discard used cartridges according to local biohazard regulations.
• Keep unopened packs in original carton at room temperature.
• Check expiry or sterilization indicators if present on packaging.
