MAST TATTOO Pro SMP 3RL 0.25mm Cartridges — 20 Pack, Clear Tip & Sterile

MAST Pro SMP 3 Round Liner cartridges are single-use, 0.25mm round-liner tattoo needles engineered for precise permanent makeup, scalp micropigmentation and hair stroke work.

These MAST TATTOO Mast Pro SMP cartridges combine a low-profile housing, clear tip visibility and a protective membrane to reduce fluid backflow and improve needle stability. Each needle is surgical stainless steel, EO gas sterilized and individually packed, making the set ready for immediate professional use. The 3 round liner (3RL) 0.25mm size is popular for crisp micro-lines, hair-like strokes and detailed lining work on the face and scalp.

How do these cartridges improve line precision?

The 3 round liner configuration concentrates pigment into a tight group of three fine needles, enabling clean, controlled strokes. The low-profile tip and clear housing let you see ink flow and needle motion clearly, so you can maintain consistent depth and pressure.

• 0.25mm needle diameter for fine, accurate lines
• 3RL grouping for dense, precise pigmentation
• Clear tip for visibility of ink and needle movement
• Low-profile shell reduces wobble and hand fatigue

What safety and hygiene features are included?

Each cartridge is individually EO gas sterilized and packaged to ensure sterility until opened. A protective membrane inside the cartridge helps prevent ink and fluid from traveling back into the machine, lowering contamination risk and keeping device components cleaner.

• 100% EO gas sterilized, single-use cartridges
• Protective membrane to block fluid entry into the machine
• Surgical-grade stainless steel needles for corrosion resistance
• Smooth-edged housing minimizes tissue trauma
