MAST TATTOO Mast Pro SMP 0403RL cartridges are pre-sterilized, surgical-steel 3 round liner needles (0.18mm) sold in a 20-piece pack for professional SMP and permanent makeup work.

These Mast Pro SMP cartridges are engineered for precision micro-pigmentation and scalp micropigmentation (SMP). Built with a protective membrane, low-profile housing and clear tips for improved visibility, they combine consistent ink flow with reduced backflow risk. Each needle is EO gas sterilized and single-packed to meet salon and clinic hygiene standards while remaining compatible with most cartridge-style pen machines.

How do these cartridges improve control during scalp micropigmentation?

The 3 round liner configuration with 0.18mm diameter needles provides a fine, concentrated point for crisp stippling and hairline detail. The clear tip improves sightlines so you can place dots with confidence, and the housing stabilizes the needle for consistent depth.

• 3-round grouping for precise dot placement
• 0.18mm surgical-grade needles for fine detail
• clear tip for better visibility and accuracy
• stabilizing housing reduces needle wobble

Are these cartridges safe and ready to use in a professional setting?

Yes — each Mast Pro SMP cartridge is individually sealed and EO gas sterilized to ensure sterility on arrival. The needles are made from surgical stainless steel and the cartridge design includes a protective membrane to prevent fluid backflow into your machine.

• single-packaging for cross-contamination control
• EO gas sterilization documented for clinical use
• protective membrane minimizes liquid ingress
• surgical stainless steel for corrosion resistance

Will these cartridges fit my pen machine or PMU device?

What performance differences should I expect compared with other cartridges?
