MAST TATTOO Mast Pro 1209RS Round Shader Tattoo Cartridges 20-Pack — Clear Disposable, Calibrated Tension

These are Mast Pro disposable 1209RS round shader tattoo cartridges — a 20-piece pack built with clear, high-density plastic bodies and calibrated tension for consistent shading and easy cleaning.

Designed for artists who want dependable disposable cartridges, the Mast Pro 1209RS round shaders combine a transparent housing with a tension system tuned to reduce stress on rotary and pen-style machines. The clear body helps you monitor ink flow and rinse between color changes, while the stable internal mount keeps needle groups aligned for smooth pigment delivery.

How do Mast Pro 1209RS cartridges improve shading consistency?

The 1209RS grouping and manufacturing tolerance keep needles evenly spaced so pigments deposit uniformly. That stability reduces skipping and feathering when building gradients or packing color.

• Round shader 9-count grouping for dense, even packs
• Calibrated tension minimizes needle wobble
• Clear housing shows ink flow and needle movement
• Disposable design eliminates sterilization concerns between clients

Will these cartridges fit my pen or rotary machine?

Mast Pro cartridges are made to work with most standard cartridge-compatible pen and rotary grips. The universal connection and stable mount make them a straightforward swap-in for compatible machines.

• Standard cartridge fitting for broad compatibility
• Secure connection reduces play during work
• Low-stress tension helps prolong pen motor life
• Disposable format for quick changes mid-session

How do I keep the cartridges clean between color changes?

The clear, high-density plastic bodies make rinsing and visual inspection simple, so you can flush residual ink and confirm the tip is clear before a new color. Because they are disposable, thorough cleaning is quick and final—replace cartridges for full hygiene.

• Transparent bodies reveal ink residue for efficient rinsing
• Rinse under running water and use approved disinfectant for external surfaces
• Replace cartridges between color switches to avoid cross-contamination
• Single-use needles eliminate repeated autoclave cycles

What needle groupings and sizes does Mast Pro offer for liners and shaders?

Mast Pro supplies a full range of needle configurations across liners and shaders so you can choose appropriate groupings for linework, shading, and packing. The 1209RS specifically targets shading with a nine-needle round formation.

• 1209RS = 9-needle round shader for even coverage
• Other Mast Pro groupings available for liners and different shader densities
• Choose grouping based on desired saturation and texture
• Consistent manufacturing keeps groupings predictable session to session

Who is this for: Mast Pro 1209RS 20-piece disposable cartridges suit professional tattoo artists and apprentices who need reliable, easy-to-clean round shaders that work with cartridge-ready pens and rotary machines. They’re ideal for shading, blending, and packing color, and for studios prioritizing efficient workflows and client safety through single-use components.
