MAST TATTOO Mast Pro 20-Pack Bugpin 0.25mm (0803) Round Liner Cartridges — Fine-Line Precision, Clear Body

MAST TATTOO Mast Pro 20-pack Bugpin round liner cartridges are disposable 0.25mm (0803) needles designed to deliver tight, precise lines and consistent ink flow for detailed tattoo work.

These Mast Pro cartridges pair a clear, high-density plastic body with needle groupings optimized for fine-line lining and delicate detail. Each pack contains 20 single-use cartridges sized 0.25mm (commonly labeled 0803) in a round liner configuration, giving artists predictable performance for tasks such as crisp outlines, micro lining, and intricate dotwork. The cartridges are engineered to fit most cartridge-style rotary and pen machines and include features aimed at reliable feed and easy visibility during color changes.

How do these cartridges help produce cleaner, crisper lines?

The 0.25mm bugpin configuration concentrates ink into a tighter point, which helps you lay down sharp outlines and fine details with less spreading. The round liner build provides a compact needle cluster that maintains a consistent tip profile throughout the stroke, reducing blowouts when used with appropriate depth and speed.

• 0.25mm (0803) bugpin size for concentrated ink delivery
• Round liner grouping for uniform, precise strokes
• Stable needle tension minimizes tip wobble and promotes crisp edges
• Clear cartridge body helps you spot ink flow and color changes

Will these cartridges work with my cartridge-style pen or rotary machine?

MAST TATTOO Mast Pro cartridges are designed to be compatible with most cartridge-compatible rotary and pen-style tattoo machines. The universal hub and secure membrane meet common industry dimensions, but confirm your machine accepts cartridge fittings before purchase to ensure a correct fit.

• Universal cartridge hub fits the majority of pen and rotary machines
• Secure membrane reduces backflow for cleaner operation
• Disposable design makes switching needles quick and sanitary

How easy are they to use and maintain during a session?

The clear high-density plastic bodies make it simple to monitor ink movement and efficiently clean the tip between color changes. Pre-assembled, single-use cartridges remove the need for needle installation and simplify teardown, letting you focus on workflow and hygiene.

• Pre-assembled disposable cartridges for fast swaps
• Clear bodies allow quick visual checks and easier tip cleaning
• Optimized needle tension helps preserve machine performance during long sessions

What should I expect in terms of consistency and reliability?

These cartridges are built to deliver repeatable performance across a pack—needle grouping, tension, and body molding are manufactured to consistent tolerances so each cartridge behaves predictably. That reliability helps artists maintain steady results from the first to the twentieth cartridge in a session.

• High-density molding for consistent cartridge shape and ink flow
• Carefully set needle tension reduces variance between cartridges
• Pack of 20 provides a dependable supply for multiple procedures or sessions
