The PMU Round Liner 3R cartridges 0.18 mm are designed for permanent makeup and cosmetic tattoo professionals who require maximum precision, control, and reliability in detailed work. Ideal for hair stroke techniques, fine outlines, and light shading, these cartridges offer high line definition thanks to the Round Liner configuration and the extremely fine diameter. The structure is designed to ensure operating comfort, stability, and a consistent ink flow throughout the procedure.

The silicone coating improves grip and reduces hand fatigue, making even longer work sessions more comfortable. The rubber supports ensure a stable connection between the machine and cartridge, improving operational smoothness.
