CNC 5RL Tattoo Needle Cartridges 20-Pack Bugpin Round Liner — 316L Stainless, Leakproof Membrane

CNC 5RL Tattoo Needles Cartridge 20Pcs are sterile, single-use round liner bugpin cartridges made from 316L surgical stainless steel with a leakproof membrane and stabilizer for precise lining work.

These CNC EN04-20-1005RL cartridges pair surgical-grade needles with medical-grade plastic bodies to deliver a dependable round-liner option for tattoo artists. Packaged individually and sterilized by E.O. gas, the 20-piece set is compatible with most rotary machines and cartridge grips. The bugpin grouping (5RL) provides tighter point concentration for crisp lines and detailed work, while the integrated membrane and stabilizer prevent fluid backflow and minimize wobble.

How do these cartridges improve precision for lining?

The 5RL bugpin configuration clusters five fine needles to produce a concentrated, sharp point ideal for clean outlines and intricate detail. The tighter grouping reduces skip and helps maintain even ink flow across strokes. A built-in stabilizer further minimizes play in the cartridge to improve consistency from the first pass to the last.

• 5 round liners arranged as a bugpin for fine, dense points
• Stabilizer reduces lateral movement for steadier lines
• Tightly grouped needles maintain continuous ink delivery
• Consistent depth and performance across the 20 cartridges

Are these cartridges safe and easy to use in a professional setup?

CNC cartridges arrive individually packaged and E.O. gas sterilized for one-time use, reducing contamination risk and simplifying clinic workflow. The plastic housing is medical-grade and the needles are 316L stainless steel — materials commonly used in professional tattoo equipment. They snap into most modern rotary machines and cartridge-style grips, enabling fast swaps between clients.

• Individually sealed, sterile cartridges for single-use safety
• Compatible with most rotary tattoo machines and cartridge grips
• Medical-grade plastic body and durable 316L needle construction
• Designed for quick installation and hygienic disposal

Will the membrane and stabilizer affect ink flow or maintenance?

The membrane creates a barrier that prevents ink and fluids from entering the grip, supporting a cleaner workstation and lowering the chance of internal contamination. The stabilizer keeps the needle cluster steady without hindering ink passage; artists will notice consistent ink delivery and less cartridge wobble. Because cartridges are single-use and sealed, routine internal grip maintenance is simplified.

• Leakproof membrane prevents backflow into the grip
• Stabilizer maintains needle alignment without restricting ink
• Reduces need for deep grip cleaning between clients
• Single-use design minimizes long-term contamination risks
