MAST TATTOO Pro2 Tattoo Cartridge Needles #12 Bugpin 5RL — 20-Count Disposable, Rotary-Compatible Precision Liners

Mast Tattoo Pro2 #12 Bugpin 5RL cartridges are single-use rotary-compatible round liner needles engineered for ultra-fine, consistent linework and smooth ink flow.

These Pro2 cartridges combine precision-ground 304L stainless steel needles with an anti-wobble plunger and a full membrane barrier to keep ink where it belongs. Designed for artists who demand dependable liners and the ability to pack fine details, each cartridge is individually sealed for hygiene and studio efficiency. They work across common rotary pen machines so you can standardize your kit without buying machine-specific heads.

How do these cartridges improve line consistency for fine detail?

The Pro2 bugpin 5RL setup uses tightly grouped, ground needles with automated tapering to maintain uniform geometry from tip to shank. That precise formation reduces skipped strokes, produces predictable needle penetration, and helps retain crisp lines even at higher speeds.

• Precision-ground 304L stainless steel for uniform tapers
• Machine-aligned grouping tolerance of ±0.02mm
• Bugpin configuration concentrates ink flow for tighter lines
• Individually packaged to protect tip integrity

Will these cartridges fit my rotary pen machine?

Yes — Mast Pro2 cartridges are engineered for cross-brand compatibility with standard rotary pen-style grips. They have been confirmed to work with Mast and Dragonhawk machines, and are compatible with most other rotary pens that accept standard cartridge connections.

• Standard cartridge interface fits common rotary pen grips
• Tested compatibility with Mast and Dragonhawk models
• One cartridge type eliminates machine-specific inventory
• Easy snap-in installation for quick swaps during sessions

What features reduce ink backflow and needle wobble?

The Pro2 design incorporates a full membrane barrier and a stabilized plunger system to block ink backflow into the grip while minimizing lateral movement of the needle. Together these elements preserve clean equipment interiors and provide steadier needle travel, which aids in clean dot retention and shaded transitions.

• Full membrane system prevents ink from entering grips and tubes
• Stabilized plunger reduces wobble for neater lines and shading
• Nozzle profile engineered to smooth ink turbulence
• Consistent sealing through extended sessions

How should I use and dispose of these disposable cartridges?

Use the cartridge per standard single-client, single-session hygiene protocols: install a sterile cartridge, perform the tattoo, then remove and dispose of it in a sharps container immediately. Do not attempt to reuse or sterilize these single-use units — disposal protects clients and keeps your kit compliant with common studio safety practices.

• Install into compatible rotary pen grip before tattooing
• Use once per client/session, then discard in an approved sharps bin
• Do not autoclave or attempt to refill
• Store unopened cartridges in a clean, dry place

Who is this for: Mast Tattoo Pro2 #12 Bugpin 5RL cartridges are geared toward professional tattoo artists and serious apprentices who prioritize consistent, ultra-fine liner performance and efficient studio workflow.
