MAST TATTOO Mast Pro 20-pack bugpin disposable cartridges (1007RL) are precision round-liner needles designed for fine lines, tight detail work, and reliable single-use convenience.
These Mast Pro purple cartridges combine a high-density clear plastic housing with finely grouped bugpin needles to deliver consistent ink flow and control. The disposable design keeps hygiene standards high, while the cartridge body’s optimized spring tension reduces vibration and stress on clip cords or pen machines. Ideal for artists who want a crisp liner for micro-detailing, the 1007RL grouping offers a tight seven-needle cluster for sharper, controlled strokes.
The difference lies in needle diameter and cartridge engineering. Bugpin needles are thinner than standard liners, producing finer, more delicate lines without sacrificing pigment saturation. Mast Pro’s clear, high-density plastic body also helps you monitor ink and clean the tip between color changes.
MAST TATTOO Mast Pro cartridges are engineered to be compatible with most cartridge-style rotary and coil pen machines. The balanced tension and standardized fit make them stable in both low- and high-speed setups, giving artists predictable line quality across sessions.
Yes. Each cartridge is single-use and disposable, reducing cross-contamination risk and simplifying cleanup. The clear tip also helps you visually confirm ink color and cleanliness between passes, streamlining workflow in fast-paced environments.
The 7-needle round liner configuration excels in precision work such as micro-lines, script, fine blackwork, and detailed portrait accents. It gives strong pigment laydown while maintaining the delicacy needed for tight curves and small text.
Who is this for: Professional tattoo artists and advanced apprentices seeking a reliable disposable bugpin round-liner that balances fine-line capability with machine-friendly engineering. These cartridges are suited for studios prioritizing precision, hygiene, and quick cartridge changes during busy appointment schedules.
Q: Are these cartridges compatible with all cartridge tattoo machines?
A: Yes, Mast Pro cartridges use a standard cartridge connection and fit most rotary and pen-style machines.
Q: How many needles come in each pack and what is the grouping?
A: Each pack contains 20 disposable cartridges, each with a 7-needle bugpin round liner (1007RL) grouping.
