MAST TATTOO Pro Cartridge Needles 50pcs Assorted — Clear RL Sizes with Anti-Spitback Membrane

MAST TATTOO Pro Cartridge Needles — a 50-piece assortment of clear-body, membrane-equipped cartridges designed for versatile lining and shading across rotary and pen-style machines.

These MAST TATTOO Pro cartridges combine a clear, high-density plastic shell with an anti-spitback membrane and a range of common needle groupings so artists can switch between liners and shaders quickly. The kit includes five popular RL (round liner) sizes and is compatible with most rotary and coil pen-style tattoo machines. Clear bodies make visual cleaning easier and help artists manage color changes and hygiene between sessions.

How do these cartridges reduce ink spitback and mess?

The cartridges use an internal membrane barrier that blocks fluids and ink from traveling back into the grip or machine. That reduces the need for frequent internal cleaning and helps maintain smoother machine performance during longer sessions.

• Membrane mechanism prevents ink spitback into the grip.
• Sealed tip and membrane minimize contamination risk.
• Clear body makes spitback or ink flow visible for quick checks.

Which needle sizes and groupings are included in the 50-piece kit?

This assortment focuses on commonly used round liners (RL) suitable for both fine detail and heavier lining. Sizes are distributed to give artists options for tight lines, thicker outlines, and transition work without buying individual cartridges.

• Includes 1205RL for very fine lining and detail work.
• 1207RL and 1209RL for medium lines and controlled shading.
• 1211RL and 1213RL for heavier lines and bold outlines.

Are these cartridges compatible with my tattoo machine?

MAST TATTOO Pro cartridges are designed with universal fit in mind and work with most rotary and coil pen-style machines that accept cartridge-style needles. Their compact, high-density plastic bodies seat securely in standard cartridge grips.

• Compatible with most rotary and coiled pen-style machines.
• Standard cartridge connection fits common grips and adapters.
• Clear plastic shells are lightweight and durable under typical use.

How do the clear bodies help during a session?

Transparent cartridge shells let the artist see ink flow, monitor tip cleanliness, and spot air bubbles or contamination quickly. That visibility supports faster color changes and easier maintenance between passes.

• See ink level and flow for consistent line work.
• Easier to inspect and clean the tip between color swaps.
• High-density plastic resists cracking while remaining lightweight.

Who is this for: This 50-piece assortment is suited to professional and aspiring tattoo artists who want a ready mix of liner cartridges for studio work, walkthrough appointments, or practice sessions. It benefits artists who prefer cartridge systems, need reliable anti-spitback protection, and appreciate the convenience of clear bodies and common RL groupings for daily use.
