Why customers choose Remedies Beauty

A-minusone 20pcs 1214RL round liner disposable cartridges are sterile, anti-backflow tattoo needles designed to deliver consistent lines and improved ink control for professional tattoo artists.

These 20 single-use 1214RL cartridges pair corrosion-resistant stainless steel needles with a clear plastic housing and a built-in membrane to prevent ink or blood backflow. Each cartridge is double-sealed and EO-sterilized so you can replace needles quickly while maintaining a hygienic workflow. The design includes a stabilizer to reduce tip wobble and a transparent tube for clear ink visibility, allowing reliable performance in a wide range of lining tasks.

How do these cartridges improve line work?

The precision-ground round liner grouping (1214RL) concentrates 14 needles in a compact formation, producing crisp, consistent strokes for outlines and detailed blackwork. The stabilized needle mount reduces lateral movement so lines stay sharp even at higher machine speeds.

  • 14-needle round liner for tight, bold or delicate lines
  • Stabilizer reduces needle wobble for cleaner strokes
  • Consistent stainless steel construction for uniform penetration
  • Clear tubes let you monitor ink flow during sessions

What safety features prevent contamination?

Each cartridge is individually double-sealed and EO-sterilized to meet single-use hygiene expectations. The integrated anti-backflow membrane and secure housing help stop ink or body fluid from entering the tattoo pen, lowering cross-contamination risk when used correctly.

  • EO-sterilized, single-use packaging for sterile handling
  • Anti-backflow membrane to block ink or blood return
  • Transparent, sealed cartridge body for visual inspection
  • Disposable after use to maintain clinic hygiene protocols

Will these cartridges fit my rotary pen and how durable are they?

These A-minusone 1214RL cartridges are designed to be compatible with most modern rotary tattoo pens that accept standard cartridge fittings. The stainless steel needles and sturdy plastic housing create a stable combination that holds up to typical lining speeds and pressures used by professionals.

  • Universal standard-fit cartridge connection for broad compatibility
  • Quality stainless steel needles resist bending and corrosion
  • Robust plastic housing maintains needle alignment during work
  • Pack of 20 supports busy sessions without frequent restocking

How do I choose, store, and dispose of these cartridges?

Select the 1214RL when you need grouped round liners for outlines, script, or dense blackwork. Store unopened cartridges in a cool, dry place away from direct sunlight; once opened, use or dispose of cartridges according to your clinic’s sharps and biohazard guidelines.

  • Choose 1214RL for outlines, micro-details, and bold lines
  • Keep unopened packs in temperature-controlled storage
  • Dispose used cartridges as regulated biohazard sharps
  • Check seals before use; do not use if packaging is damaged

Who is this for: Professional tattoo artists, apprentices in training, and studio owners who require sterile, reliable round liner cartridges for daily lining tasks. This 20-pack suits busy tattooists needing consistent needle performance, quick cartridge swaps, and straightforward compatibility across most rotary machines.
