Mast Pro Cartridge Needles – Extra Tight Round Liner (0.25mm Diameter, 7MM Taper)

Built for permanent makeup and tattoo artists who need absolute control, the Mast Pro Extra Tight Round Liner Cartridge Needles 0.25mm deliver consistent, professional-grade results using an extra-tight pin grouping for the darkest, most saturated outline 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.

An Extra Tight Round Liner is a further refinement of the tight round liner configuration, with needle pins grouped even closer together at the tip. This produces the crispest, darkest, most saturated outlines available in a round liner format, with minimal passes needed and reduced skin trauma. The 0.25mm diameter combined with a 7MM taper gives artists the precision needed for bold eyebrow and eyeliner outlining, lip lining, and dense linework in cosmetic and tattoo applications, without sacrificing control or comfort during longer sessions.

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 bold eyebrow and eyeliner outlining, lip lining, and dense linework in cosmetic and tattoo applications. 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.
