Mast Pro RL needle cartridges represent a solid balance between technology, safety, and professional performance. Created by Mast Tattoo, a recognized brand in the world of tattoo supplies, these cartridges were designed for artists who work with detail, demand stability, and insist on clean results from the very first stroke.

Each cartridge incorporates a unique stabilization system that keeps the needle steady throughout the entire movement. The result is immediately noticeable on the skin. The lines come out more controlled, uniform, and predictable, even in delicate work or prolonged sessions. This translates to fewer corrections, less stress, and greater confidence during the process.

The internal protective membrane is one of the key points of this system. It prevents the backflow of ink and liquids into the machine, protecting the equipment and ensuring a safer and more hygienic working environment. The sealed construction around the needle bar contributes to efficient ink absorption and a constant release, without skips or splashes.

The transparent cartridge body significantly improves visibility. It allows you to monitor the ink flow in real time and adjust your technique precisely. The low-profile housing was designed to optimize internal flow and reduce skin trauma, which is especially relevant for continuous lines, technical work, or permanent makeup procedures.

The needles are made of surgical stainless steel , sterilized with EO gas, and individually packaged. Every detail has been carefully considered to meet the demands of a professional tattoo studio, where safety, consistency, and efficiency are part of the daily routine.

Compatible with virtually all cartridge machines and handpieces, including rotary handpieces and PMU equipment, these cartridges easily adapt to different styles and working methods, without the need for complex adjustments.

Frequently Asked Questions

Are Mast Pro RL cartridges compatible with my tattoo machine?

Yes. Mast Pro RL cartridges are universal and compatible with virtually all machines and cartridge grips on the market, including rotary pen machines and permanent makeup equipment. If your machine uses a standard Cheyenne-type cartridge system, you will be able to work without any adaptation.

What is the difference between Mast Pro RL and other round liner cartridges?

The main difference lies in the needle stabilization and ink flow control. The Mast Pro series was developed with a more precise internal system that reduces vibrations, improves line consistency, and prevents variations during the stroke. This translates into cleaner lines, less trauma to the skin, and a more professional result, especially in demanding work.

Are these cartridges suitable for fine lines and detail work?

They are especially suited for this. The Mast Pro RL brushes were designed for technical linework, fine details, and precise contours, maintaining stability even in long or repeated strokes. The different diameters available allow you to adjust exactly the type of line you want to execute, from micro lines to more pronounced contours.

Do Mast Pro RL needles have a safety system to prevent ink reflux?

Yes. Each cartridge includes an internal protective membrane that prevents the backflow of ink, blood, or fluids into the machine. This protects your equipment, improves studio hygiene, and reduces the risk of cross-contamination, which is essential in any professional environment.
