MAST TATTOO Mast Pro Cartridge Needles 1214RL are a box of 20 sterile, disposable round-liner cartridges designed for consistent line work and smooth ink flow.

These Mast Pro purple cartridges combine a high-clarity plastic housing, an anti-backflow membrane, and calibrated needle tension so artists can rely on uniform performance session after session. Supplied as standard-size round liners (1214RL), the set is intended for general-purpose outlining and detailed linework on rotary or cartridge-compatible pen machines.

What makes these cartridges consistent for outlining?

The cartridges are engineered with balanced needle tension and precision assembly to reduce wobble and maintain stable penetration depth. A clear, high-density plastic body helps you visually confirm ink level and needle movement while working.

• Balanced tension reduces stress on rotary pen motors.
• Clear housing offers quick visual checks when changing colors.
• Precision-mounted needle grouping keeps lines crisp.

How do they control ink spitback and hygiene?

Each cartridge includes an internal membrane that limits ink and fluid backflow into the machine, improving cleanliness and reducing contamination risk. They are disposable after single use, helping studios maintain high hygiene standards.

• Integrated membrane prevents ink spitback into the grip.
• Single-use design supports cross-contamination protocols.
• Clear tip simplifies visual cleaning between color changes.

Will these work with my tattoo pen machine?

These Mast Pro cartridges are made to fit most standard cartridge-compatible rotary and pen-style tattoo machines. The standard 1214RL round-liner configuration is a common format that suits many grip and adapter systems.

• Standard cartridge fitting for most tattoo pens and grips.
• Suitable for both rotary and pen-style machines that accept cartridges.
• Works well for a range of needle groupings used in outlining.

What practical benefits do artists notice during use?

Artists often report smoother tattooing sessions due to the cartridge’s calibrated tension and fluid ink delivery. The materials and membrane reduce interruptions from spitback and make color switches quicker thanks to the see-through body.

• Less machine strain from tuned needle tension.
• Faster color changes because tips are clear and easy to inspect.
• Reliable, predictable line performance for detailed work.
