MAST TATTOO Pro Cartridge Round Liner Needles 1201RL — 20pcs Disposable, Reduced Spitback Clear Housing

MAST TATTOO Mast Pro Cartridge 1201RL is a disposable 20-piece pack of standard round liner tattoo cartridges engineered for consistent ink flow, reliable tension, and reduced spitback during lining work.

Designed for professional tattoo artists and serious hobbyists, these Mast Pro purple cartridges combine a clear, high-density plastic body with an internal membrane to help prevent ink spitback and make color or tip changes easier. The pack contains 20 single-use round liner (1201RL) cartridges sized for precise line work, offering dependable performance across both tight details and everyday outlining.

How do these cartridges improve line consistency?

The 1201RL round liner construction centers the needle and stabilizes movement, yielding cleaner, more predictable strokes. The cartridge's tension is tuned to ease strain on rotary and pen-style machines so your lines stay steady over long sessions.

• Standard 1201RL single-needle round liner for precise thin lines
• Balanced internal tension reduces needle wobble
• Clear body helps monitor ink level and needle alignment

What prevents ink spitback and keeps the workflow cleaner?

Each cartridge includes a membrane barrier between the needle channel and the grip, limiting ink and fluid return into the machine. That membrane plus the tapered tip design helps maintain a more hygienic setup and decreases interruptions to wipe or adjust equipment.

• Internal membrane to reduce spitback and machine contamination
• Tapered disposable tip for controlled ink delivery
• Easy-to-clean clear housing for quick color changes and inspections

Are these cartridges compatible with common tattoo pens and machines?

MAST TATTOO Mast Pro cartridges are built to fit most standard cartridge-style rotary and pen machines used by professionals. Their standardized hub and size ensure a secure connection while still allowing fast swaps mid-session.

• Standardized cartridge hub works with most cartridge-capable machines
• Disposable format simplifies sanitation and setup between clients
• Durable plastic holds tension across varying machine outputs

How do these cartridges support hygiene and studio efficiency?

Being single-use disposables, the Mast Pro cartridges eliminate the need for needle sterilization and reduce cross-contamination risk. The clear plastic body makes it straightforward to confirm a clean tip and membrane before use, speeding prep time and client turnover.

• Single-use disposal lowers infection risk and simplifies compliance
• Clear cartridge body makes contamination checks fast and reliable
• Pack of 20 keeps a ready supply for busy sessions or touch-ups
