MAST TATTOO 1201RL Round Liner Cartridge Needles — 20pc Disposable, Clear Purple Housing with Anti-Spitback

These Mast Pro cartridge needles are a standard-size 1201RL round liner packaged in sterile, single-use cartridges. Built with a transparent purple-tinted, high-density plastic housing, they offer visible ink flow and an internal membrane to reduce spitback. The cartridges are engineered to maintain balanced tension, helping your rotary or pen-style tattoo machine run with less strain while delivering consistent needle performance.

How do these cartridges improve line consistency?

The 1201RL configuration concentrates a single needle for tight, precise liners. The cartridge’s steady tension and straight needle alignment make strokes smoother and more predictable, helping artists achieve clean outlines and crisp details.

• Standard 1201RL single-needle round liner for precise lines
• High-density clear plastic reveals ink feed and needle position
• Optimized tension reduces needle wobble during long sessions

Will these cartridges reduce spitback and mess?

Yes — each cartridge includes a membrane barrier that limits ink spitback and keeps the machine’s grip area cleaner. That barrier also protects the internal mechanism and makes the tattooing process feel more controlled and hygienic.

• Internal membrane prevents ink from flowing back into the grip
• Clear body simplifies visual checks and prevents unexpected splatter
• Disposable design eliminates reuse-related contamination risks

Are these cartridges compatible with my tattoo pen or machine?

MAST TATTOO Mast Pro cartridges are designed to fit most cartridge-style rotary and pen machines that accept standard snap-in cartridges. Their reliable hub and consistent tension make them suitable for many modern machines used by professional artists.

• Standard cartridge connector fits most cartridge-compatible pen/rotary systems
• Engineered tension for smooth performance on prolonged sessions
• Single-use disposability keeps cross-contamination risks low

How do I maintain hygiene and performance between color changes?

The transparent body makes it easier to flush and inspect the tip between color swaps, while the single-use nature ensures you can change cartridges quickly without worrying about sterilization. Always dispose of used cartridges following local biomedical waste regulations.

• Clear housing allows quick visual cleaning checks
• Swap cartridges to change colors without deep sterilization steps
• Discard after single use to keep studio hygiene compliant
