Mast Pro Tight Round Liner Cartridge Needles (0.35 mm Diameter, 3.5 mm Taper)

Built for artists who need crisp, dense, and highly controlled linework, the Mast Pro Tight Round Liner cartridge needles 0.35mm deliver dark, consistent lines for eyebrow outlining, eyeliner, lip lining, and precision tattoo work. Each box contains 20 sterile cartridges engineered from premium 304L stainless steel, polished by automatic machinery for an exceptionally smooth glide through the skin.

A Tight Round Liner is a specialized variation of the standard round liner needle, where the individual needle pins are soldered or grouped significantly closer together at the tip. This concentrated configuration produces extremely crisp, dark, and consistent lines without causing excess skin trauma, making it ideal for outline work that demands maximum line density and saturation.

Why Artists Choose Mast Pro Tattoo Needles

Professional tattoo and PMU artists test each Mast Pro cartridge before release and individually inspect each needle thread for consistency. The cartridge and needle are matched for perfect compatibility, so ink flows smoothly and evenly with no clogging or impurities, supporting clean results across microshading, powder brow, and lip blush techniques. An advanced visual optimization tube, featuring a key-head-shaped shell and precisely angled sides, reduces lens distortion and refraction, giving artists a clearer view of the needle tip while working. Four reinforced bars inside the cartridge add durability and strength while keeping the needle responsive under pressure.

Sterilized with ethylene oxide, every cartridge is intended for single use, supporting strict hygiene standards in professional PMU and cosmetic tattoo settings.
