Mast Pro Cartridge Tattoo Needles (20-pack, 1209RL) are single-use round liner cartridges designed to deliver consistent, smooth lines with a clear high-density plastic body and anti-spitback membrane.

These Mast Pro purple cartridge needles come ready-to-use in a standard 1209RL configuration, engineered for tattoo artists who want dependable performance and easy maintenance during sessions. The cartridges pair with most cartridge-style tattoo pens, offer a visible ink path for quick color changes, and include a membrane to reduce ink backflow for tidier operation. Below you'll find practical answers to common questions artists ask when choosing round liner cartridges.

How do these cartridges affect line quality and control?

The 1209RL grouping places nine tightly packed needles into a round formation, giving crisp, consistent lines suitable for fine outlines and detail work. The clear, rigid plastic housing maintains needle tension and alignment, so you get predictable results shot after shot.

• Standard 1209RL configuration for sharp outlining and detail
• High-density plastic body preserves needle straightness and tension
• Uniform needle spacing reduces wobble and inconsistent strokes

Will these cartridges help keep my machine cleaner and easier to switch colors?

The transparent cartridge body makes it simple to see residual ink, speeding color swaps and helping with quick in-session cleaning. An internal membrane system prevents ink from traveling back into the machine, reducing the chance of contamination and simplifying maintenance between passes.

• Clear housing for visible ink flow and easier color changes
• Membrane reduces spitback and protects the grip/pen internals
• Disposable single-use design removes need for lengthy sterilization

Are these cartridges compatible with my equipment and suitable for long sessions?

MAST TATTOO Mast Pro cartridges fit most universal cartridge-style tattoo pens and are built to keep steady tension so the pen operates smoothly during extended use. Their construction is intended to reduce stress on the pen’s motor and mechanism, which helps maintain consistent performance over longer sessions.

• Universal cartridge fit works with many cartridge tattoo pens
• Optimized tension minimizes strain on the machine during long runs
• Single-use disposability supports hygiene and workflow efficiency

What safety and practical features should I expect from these 20-piece boxes?

• Individually sealed for single-use safety
• Membrane-equipped tips to prevent ink backflow and reduce cleanup
• 20-count box gives a good working supply for multiple clients or extended sessions
