MAST TATTOO Mast Pro Cartridge Needles 1214RL Round Liner 20-Pack — Disposable, Pre‑Sterilized Precision

MAST TATTOO Mast Pro 1214RL are single-use round liner cartridge needles designed for precise linework and reliable ink flow in a 20-piece sterile pack.

These Mast Pro cartridge needles pair a clear, high-density plastic housing with a membrane system to reduce spitback and keep ink delivery stable. The standard size 1214RL round liner grouping is intended for controlled, consistent lines; cartridges fit most cartridge-style rotary and pen machines. Each box contains 20 disposable, pre-sterilized cartridges to streamline setup and help maintain a hygienic workflow.

How do these cartridges improve line precision?

The 1214RL round liner grouping concentrates needle points for clean, sharp lines while the rigid cartridge body minimizes flex during use. Together they help artists maintain steady hand control and repeatable results across sessions.

• Round liner 1214RL grouping for tight, defined lines
• High-density plastic housing reduces wobble under pressure
• Pre-aligned needle tips for consistent stroke width
• Disposable design avoids needle deformation from repeated sterilization

Will these cartridges prevent ink spitback and mess?

Yes — the built-in membrane system helps stop ink from traveling back into the machine, reducing splash and keeping the grip cleaner. That containment protects the motor area and simplifies cleanup between color or client changes.

• Membrane barrier reduces ink reflux and spitback
• Clear cartridge body makes residual ink visible for easier cleaning
• Sealed tip design limits aerosolized ink during heavy lining

Are these compatible with my tattoo pen or rotary machine?

Mast Pro cartridges are made to fit most industry-standard cartridge-style grips and pen machines. Their standardized connection and robust plastic shell allow broad compatibility, but confirm your device accepts cartridge-style needles before ordering.

• Standard cartridge fitting for most cartridge-compatible pens and rotary units
• Rigid connection minimizes play between cartridge and grip
• Disposable format works with quick-swap workflows

How do these cartridges support hygiene and workflow efficiency?

Single-use sterile packaging reduces cross-contamination risk while clear bodies and controlled tension speed routine changes. Artists can switch colors or clients with fewer steps, maintaining a consistent machine feel thanks to balanced tension in the cartridge design.

• Individually sterile cartridges limit contamination risk
• Clear housings let you inspect and clean the tip between color swaps
• Balanced internal tension preserves pen performance over long sessions
• 20-pack supply supports busy schedules without frequent repurchasing

Who is this for: Mast Pro 1214RL cartridges are built for professional and advanced-enthusiast tattoo artists who demand reliable round liners for precise linework and hygienic, efficient swap-outs. They suit studio environments where compatibility with cartridge-style pens and reduced ink spitback are priorities, and for artists who prefer disposables to maintain consistent needle performance and clinic-level sanitation.
