CNC 5RL Tattoo Needle Cartridges 20pc — 12mm Standard Round Liner, Sterile Disposable with Membrane

CNC 5RL tattoo cartridge needles are a 20-piece pack of sterilized, disposable round liner cartridges (12mm standard) built for precise lining and reliable machine compatibility.

These CNC cartridges combine surgical-grade 316L stainless steel with medical-grade plastic bodies, arriving individually E.O. gas-sterilized and sealed for single-use safety. Each cartridge is designed to fit most rotary tattoo machines and cartridge grips, offering a stable needle group with an integrated membrane that prevents fluid ingress. The pack delivers consistent 5-round-liner performance, making setup quick and hygienic for studio or mobile use.

How do CNC 5RL cartridges protect hygiene and prevent contamination?

Every needle arrives in its own sterile blister after E.O. gas sterilization and is intended for one-time use to reduce infection risk. A built-in membrane blocks ink and fluids from entering the grip, and the plastic housing uses medical-grade components for safe handling.

• Individually E.O. gas-sterilized packaging
• Disposable single-use design
• Secure membrane prevents fluid backflow into the machine
• 316L stainless steel needles for corrosion resistance

Will these cartridges work with my tattoo machine and grips?

CNC cartridges use the common cartridge interface standard and are compatible with most popular rotary machines and universal cartridge grips. They are designed to seat snugly so the needle travel remains consistent and wobble is minimized for accurate lines.

• Universal fit for most rotary tattoo machines
• Stable connection reduces needle play
• Standard 12mm cartridge length for typical grips
• Ready to install—no modification required

What kind of performance and line quality can I expect from a 5RL CNC cartridge?

The 5-round liner grouping provides clean, precise lines suitable for medium to fine outlining, script work, and detail reinforcement. Stabilizers inside the cartridge reduce lateral movement so each stroke produces predictable ink delivery and crisp hairlines or borders.

• 5-round arrangement for balanced ink flow
• Stabilizer minimizes needle wobble for straighter lines
• Consistent depth and travel improve repeatability
• Good for outlines, lettering, and refined details

How are CNC cartridges packaged and what comes in the box?

The product comes as a pack of 20 individually sealed cartridges, each marked and ready for single-use deployment in a professional setting. Clear labeling and protective packaging make inventory and compliance easier for busy studios.

• 20 sterile cartridges per package
