MAST TATTOO Pro2 Round Shader Needle Cartridges 50-Count Mixed 3RS–11RS with Membrane for Smooth Shading

MAST TATTOO Pro2 #12 Round Shader cartridges are disposable, membrane-protected tattoo needle cartridges sold as a 50-count mixed pack (10 each of 3RS, 5RS, 7RS, 9RS, 11RS) designed for precise shading and smooth ink flow.

Engineered for professional tattooists, the Pro2 line focuses on consistent performance and ease of use. Each cartridge features razor-sharp steel needles and a full membrane barrier to reduce ink backflow, while the upgraded pin design improves glide and control during shading work. The mixed-size pack covers a wide range of shading tasks, from tight details to broader fills, and is compatible with most cartridge grips and machines.

How do these cartridges improve shading control?

The Pro2 round shader configuration delivers predictable ink distribution and a smooth drag across skin. Upgraded needle pins and a stabilizing cartridge system reduce wobble, making transitions and gradients more manageable.

• Mixed sizes (3RS–11RS) let you choose finer or wider coverage instantly.
• Stabilizing system minimizes needle flex for consistent lines and fills.
• Razor-sharp steel points improve pigment pickup and release.

What measures protect against ink backflow and contamination?

Each cartridge includes a full internal membrane that prevents ink and bodily fluids from entering the grip, which helps protect your equipment and maintain hygiene standards. The disposable build means you replace the entire cartridge after use, removing cross-contamination risk.

• Full membrane barrier blocks backflow into the machine or grip.
• Disposable materials ensure single-use sterility and quick changeover.
• Individually sealed packaging preserves cleanliness until use.

Which tattoo machines and grips are these cartridges compatible with?

MAST TATTOO Pro2 cartridges are made to fit most universal cartridge-style grips and rotary or pen-style machines. Their standardized connection and compact housing work with a wide range of professional setups, simplifying kit management.

• Compatible with common cartridge grip systems and pen machines.
• Standardized hub design for secure, wobble-free mounting.
• Works across lining, shading, and filling workflows with the right needle size.

How does the mixed-size pack save time in the shop?

Having ten cartridges of each RS size (3RS, 5RS, 7RS, 9RS, 11RS) reduces interruptions during sessions and lets you switch to the correct shader quickly. The assortment covers fine detail and larger shading zones without needing separate orders.

• 50 cartridges per pack: ten of each size for consistent supply.
• Mix of 3RS–11RS handles everything from subtle shading to broad fills.
• Fewer machine adjustments and faster session flow with quick swaps.

Who is this for? MAST TATTOO Pro2 #12 Round Shader cartridges suit professional and semi-professional artists who need reliable, disposable shading needles that balance precision with throughput. If you run a busy studio, perform frequent shading and gradient work, or prefer cartridge systems for quick changes and sanitary practice, this mixed 50-count pack provides a practical, high-performance option without committing to single-size boxes.
