MAST TATTOO 3 Round Shader Cartridges 0.3mm — 20pc EO-Sterile, Membrane-Protected for Smooth Shading

High-precision Mast Pro SMP 3 Round Shader cartridge needles (0.3 mm) are sterilized, membrane-protected tattoo cartridges built for smooth ink flow and consistent shading.

These Mast Tattoo Mast Pro SMP cartridges are engineered for permanent makeup and scalp micropigmentation work where fine control and reliable pigment delivery matter. Each cartridge combines a low-profile housing, clear tip for visibility, and a protective membrane to prevent backflow into your machine. Needles are surgical stainless steel and EO gas sterilized, packaged individually to preserve hygiene and reduce cross-contamination risk.

How do these cartridges improve shading and color saturation?

The 3 Round Shader (RS) configuration concentrates three tightly grouped needles to deposit pigment evenly for soft blends and solid fill. The 0.3 mm gauge balances smooth ink pickup with minimal tissue trauma for cleaner transitions. A low-profile inner shape and optimized needle bar help maintain consistent saturation across strokes.

• Three-needle cluster for even shading and smooth gradients
• 0.3 mm diameter for controlled pigment placement
• Low-profile housing improves ink flow and stroke accuracy
• Clear tips increase visibility for precise work

Are these cartridges compatible with my tattoo or PMU pen?

Mast Pro SMP cartridges are made to fit most cartridge-style rotary and pen machines that accept standard cartridge interfaces. The universal connection and compact housing make them interchangeable with many brands, including Mast Tattoo pen models. Always confirm your device uses cartridge-style fittings before purchase.

• Standard cartridge interface fits most pen-style and rotary machines
• Works with Mast Tattoo pens and many other brands
• Easy snap-in installation and removal for quick workflow

What safety and sterility features are included?

Each needle assembly is made from surgical-grade stainless steel, sterilized with EO gas, and sealed individually to maintain sterility until use. The protective membrane inside every cartridge prevents fluids from entering the machine, helping protect the motor and reduce contamination risks. Smooth-edged housings are shaped to minimize skin trauma during procedures.
