MAST TATTOO Tattoo Cartridge Needles Assorted Pack 50 — Round Liners 1RL–9RL, Sealed Membrane, Clear Body

MAST TATTOO 50-piece assorted disposable cartridge needles are mixed round liner sizes (1RL–9RL) with a sealed membrane and clear high-density body for consistent, low-spitback tattooing.

These MAST TATTOO cartridges combine multiple liner sizes in one pack so artists can switch quickly between fine single-needle lines and broader liner groups without changing needle systems. Each cartridge is built with a transparent, high-density plastic housing that makes tip cleaning and ink monitoring simple. The internal membrane reduces ink spitback and helps keep the rotary or pen machine cleaner during long sessions. Designed to fit most cartridge-style tattoo machines, this selection covers common liner needs for outlining, detail work, and crisp line variation.

Which needle sizes are included and what can I use each for?

The pack includes 1RL, 3RL, 5RL, 7RL, and 9RL round liner cartridges, offering a progression from ultra-fine single-needle detail to medium-width lining. Use the smallest sizes for hairlines and intricate detail, medium sizes for most outlines, and larger rounds for bolder contour lines or faster coverage during lining.

• 1RL — extreme detail and micro-lines
• 3RL — fine outlines and delicate features
• 5RL — versatile everyday lining
• 7RL — stronger contouring and faster strokes
• 9RL — bold outlines and durable edges

How does the membrane and clear body improve workflow?

The sealed membrane in each cartridge significantly reduces ink spitback, which helps keep the machine, workstation, and artist cleaner. The clear, high-density plastic housing lets you monitor ink flow and makes tip cleaning between color changes faster and more reliable.

• Membrane reduces ink splash and backflow
• Transparent body for quick visual checks of ink
• Easy tip access speeds up rinsing and maintenance

Are these cartridges compatible with my tattoo machine?

MAST TATTOO cartridges are designed for broad compatibility with most cartridge-style rotary and pen machines, including many popular coil machine adapters. They click into standard cartridge grips and can be used for both lining and light shading tasks depending on size and technique.

• Fits most pen-style and rotary cartridge systems
• Quick-snap cartridge connection for common grips
• Disposable design minimizes sterilization needs

What should I expect from build quality and reliability?

These cartridges use high-density plastic for rigid, predictable needle performance and consistent needle grouping. The disposable format reduces cross-contamination risk and the variety pack ensures you have multiple sizes on hand to match client needs without changing setups mid-session.

• Durable cartridge housing maintains needle alignment
• Membrane adds protection against machine contamination
• Mixed-size pack keeps common liner gauges readily available
