STIGMA Bugpin Tattoo Cartridges 3RL Round Liner — 50-Pack Disposable Sterile Membrane, Fine Detail

STIGMA #10 (3RL) Bugpin disposable tattoo cartridges are sterile, membrane-protected round liner needles in a 50-piece pack engineered for precise, clog-resistant lining and fine detail work.

These EN05-series cartridges combine 304 surgical stainless steel needles with medical-grade plastic housings and a one-way membrane to prevent ink backflow. E.O. sterilized and packed in individual blister packs, they are built for cartridge-compatible machines and grips. The bugpin 3RL configuration offers tighter grouping for clean, sharp lines and refined detailing while the rubber-loaded design provides consistent needle rebound.

How do these cartridges deliver sharper lines and better control?

The bugpin 3RL uses smaller-diameter pins grouped in a round-liner formation to place pigment with higher definition and less trauma to skin. A sloped needle tip geometry supports smoother skin entry, resulting in more predictable ink placement and cleaner edges.

• 3RL bugpin grouping for tighter lines and finer detail
• Sloped round tips for reduced drag and precise penetration
• Rubber band loading for consistent needle return and control

What safety and hygiene features are built into the EN05 cartridges?

Each cartridge is E.O. (ethylene oxide) sterilized and sealed in its own blister to ensure sterility until use. The integrated one-way plastic membrane blocks ink and fluid from migrating into the machine or tube, lowering contamination risk during sessions.

• Individually blister-packed and E.O. sterilized for single-use safety
• Membrane barrier prevents ink backflow into grips and machines
• Medical-grade materials minimize reactions and ensure durability

Will these cartridges fit my tattoo machine and how easy are they to swap during sessions?

STIGMA EN05 cartridges are designed to be compatible with standard cartridge-style tattoo machines and most grips on the market. Their snap-in design makes changes quick and secure, helping maintain workflow and reduce downtime between color or needle-size swaps.

• Standard cartridge connection fits most rotary and coil cartridge machines
• Quick snap-in swap for efficient session transitions
• Uniform dimensions for predictable depth and needle alignment

How durable and clean is the needle construction for daily studio use?

Needles are made from 304 surgical stainless steel and housed in medical-grade plastic for a balance of strength and smooth action. The rubber-loading mechanism and consistent manufacture tolerances help maintain performance across multiple cartridges in a busy studio.

• 304 surgical stainless steel resists corrosion and bends
• Medical-grade plastic housing reduces friction and eases cleaning of surfaces
• Quality control ensures consistent needle grouping and performance
