Mast Tattoo Pro 0401RL Ultra-Fine Round Liner Needles — 0.18mm for Precise Permanent Makeup

Elevate your PMU toolkit with Mast Tattoo Pro SMP 0401RL

The Mast Tattoo Pro SMP line is designed for precise control and reliable performance in permanent makeup and microblading workflows. The 0401RL ultra-fine round liner measures 0.18 mm, offering crisp, controlled lines and steady pigment placement for detailed work.

Key design features help you focus on technique rather than tool setup. A protective membrane reduces liquid ingress and keeps the needle assembly stable, while the tips are encased around the needle bar to support consistent pigment flow and clean pigmentation across strokes and fills.

Safety and sterility are built in. The needles use surgical stainless steel, are 100% EO gas sterilized, and come in individually packaged units. The low profile housing improves visibility and reduces ink buildup, while the interior geometry supports smooth ink flow and gentler tissue interaction.

Compatibility is broad. These cartridges are easy to use and can be matched with most tattoo devices, including Mast tattoo pens and other PMU machines with cartridge interfaces. This makes it convenient to experiment with techniques or run a mixed toolkit with different brands.
