These are MAST TATTOO Mast Pro 1207RS round shader disposable cartridges: a pack of 20 clear-body, high-density needle cartridges engineered for consistent shading and easy color changes.

Designed for professional and apprentice artists who use cartridge-style rotary or pen machines, these Mast Pro cartridges combine a transparent plastic housing with calibrated needle tension to keep the pen running smoothly. The 1207RS grouping is a tight round shader configuration ideal for soft fills, gradients, and detail shading. Each cartridge is single-use for hygiene and convenience.

How do these cartridges affect machine performance?

The Mast Pro cartridges are built with optimized internal tension to reduce stress on rotary and pen machines, helping maintain steady stroke and longevity. The consistent draw ensures predictable ink flow for repeatable results.

• Engineered tension to lower motor strain
• Uniform needle alignment for smooth ink delivery
• Compatibility with most cartridge-style tattoo pens

What makes the clear plastic body useful during sessions?

The transparent housing lets artists monitor ink and tip cleanliness so color changes and tip maintenance are faster and more accurate. Visibility also aids in detecting clogs or ink pooling before they affect the work.

• High-density clear plastic for quick visual checks
• Easier cleaning of the tip area between pigment swaps
• Reduced downtime when changing colors or troubleshooting

Are these cartridges suitable for lining and shading?

While marketed as round shader needles, the Mast Pro lineup includes various groupings, and 1207RS works well for soft fills, small-area shading, and nuanced gradients. For tight liners you can choose corresponding liner cartridges in the Mast Pro series.

• 1207RS grouping optimized for shading and soft fills
• Part of a broader Mast Pro range covering liners and shaders
• Single-use disposability supports hygiene protocols

How does a 20-pack help a busy studio?

A 20-piece pack provides enough cartridges for multiple clients or longer sessions without frequent reordering, while keeping inventory manageable and sterile. The uniform cartridges simplify setup and reduce time spent adjusting different needle fittings.

• Twenty disposable cartridges per pack for convenience
• Consistent performance across all pieces for predictable results
• Saves setup time and minimizes cross-contamination risk
