MAST TATTOO Pro2 Bugpin 3RL Tattoo Cartridges, #10 20-Count — Precision Stainless Steel, Full Membrane

MAST TATTOO Pro2 #10 Bugpin 3RL cartridges are disposable, precision-ground round liner needles designed for fine, consistent linework and controlled ink flow in rotary tattoo pen machines.

This 20-count pack of Pro2 bugpin 3RL cartridges combines very fine needle tips with a stabilized cartridge body to help artists produce crisp lines and detailed work. Built from high-grade stainless steel and fitted with a full membrane barrier, these cartridges aim to reduce wobble, prevent ink backflow, and fit most rotary pen-style machines used in studios today. Whether you’re outlining delicate script or adding intricate details to a small design, the Pro2 3RL cartridges are made to deliver predictable performance session after session.

How do these cartridges improve line precision?

The bugpin 3RL grouping uses three tightly clustered, extra-fine needles with a refined taper to produce very thin, sharp lines and precise hairlines. The automated grinding process ensures each needle matches the same geometry so strokes are consistent across the pack.

• Precision-ground 304L stainless steel points for uniform tip shape.
• Close needle grouping reduces ink spread for crisp outlines.
• Machine-aligned tolerances (+/-0.02 mm) for repeatable results.

Will these cartridges work with my rotary pen machine?

Pro2 cartridges are designed for broad compatibility with rotary pen-style machines, so you don’t need machine-specific heads for most brands. They have been tested to fit common pen machines including Mast and other industry-standard rotary pens.

• Fits Mast and many third-party rotary pen systems.
• Standard cartridge connection for quick swaps between designs.
• Works with both beginner and professional pen setups.

Do they help prevent ink backflow and contamination?

Each cartridge includes a full membrane barrier that blocks ink from traveling into the grip and tube, helping preserve equipment cleanliness. The integrated plunger membrane creates a secure seal that maintains consistent performance throughout a session.

• Full membrane barrier prevents ink backflow and device contamination.
• Sealed plunger system keeps the cartridge hygienic during use.
• Individually packaged to protect sterility until opened.

How do these cartridges handle ink flow and stability during long sessions?

The nozzle profile and stabilized plunger minimize turbulence and needle wobble, allowing steady ink delivery at varying speeds. This design reduces the chance of ink pooling or splatter and supports consistent shading and lining through extended work periods.

• Nozzle shaping reduces ink turbulence for even distribution.
• Stabilized plunger design limits needle wobble under continuous use.
• Durable tip rigidity helps retain performance across multiple passes.
