MAST TATTOO Mast Pro Cartridge Tattoo Needles 20-Pack 1203RL Purple 3RL Round Liner — Sterile, Anti-Spitback

MAST TATTOO Mast Pro Cartridge 1203RL is a box of 20 disposable round liner tattoo cartridges engineered for consistent, low-friction lining with a clear high-density plastic body and anti-spitback membrane.

These Mast Pro purple cartridges (model 1203RL) come in a standard round liner configuration ideal for clean, repeatable line work. Each sterile, single-use cartridge combines a transparent housing for quick visual cleaning with a sealed membrane that helps keep ink from spitting back into the machine. The cartridge’s calibrated tension is designed to reduce strain on rotary or pen-style tattoo machines, helping the device maintain smooth performance during sessions.

How do these cartridges improve lining and detail work?

Mast Pro 1203RL cartridges are configured as round liners, grouping three needles to create crisp, consistent lines. The construction keeps needle alignment stable so artists can control line weight and flow with predictable results.

• Three-needle round liner (3RL) for fine to medium outlining
• Stable needle grouping reduces wobble for sharper lines
• Clear housing helps verify needle condition and ink flow

What safety and cleanliness features are included?

The cartridges are disposable and arrive sterile, eliminating the need to handle or sterilize needles between clients. A built-in membrane reduces ink spitback into the machine, and the clear plastic body makes it faster to spot residue when switching colors.

• Single-use, sterile packaging for hygienic handling
• Membrane system reduces ink spitback inside the machine
• Transparent body allows quick visual checks during use

Will these cartridges work with my tattoo pen or rotary machine?

Mast Pro cartridges are designed for compatibility with most cartridge-ready rotary and pen-style tattoo machines. Their standardized hub and calibrated tension deliver consistent performance across popular pen systems, while limiting extra stress on the motor during extended sessions.

• Universal cartridge fit for many pen-style and rotary grips
• Calibrated tension reduces machine strain and needle bounce
• Fits standard cartridge-compatible grips without adapters

How do they perform in multi-color or long sessions?

The clear, high-density plastic body simplifies color changes by making it easy to see ink residue in the tip area. Because each cartridge is single-use, artists can swap colors quickly without cross-contamination concerns, maintaining workflow speed and pigment purity across long appointments.

• Easy-to-clean visual inspection speeds color swaps
• Disposable design prevents cross-color contamination
• Stable tension supports longer continuous use when needed

Who is this for: The Mast Pro Cartridge 1203RL box of 20 is suited to professional and aspiring tattoo artists who prioritize consistent line quality, hygienic single-use supplies, and seamless compatibility with cartridge-style pens and rotary machines. It’s a practical choice for artists who do fine line work, lettering, or any projects requiring repeatable, clean outlines while keeping setup and color changes efficient.
