BIGWASP 50-piece assortment of #12 standard round liner (RL) tattoo needle cartridges gives artists a ready mix of precise, individually sealed liners compatible with most rotary and Hawk machines.

Designed for professionals and serious hobbyists, this pack bundles five common #12 RL configurations so you have immediate options for outlining, fine details, and bold lines without rummaging for separate cartridges. Each cartridge is individually sealed to ensure sterility until opened, features a rubber-band loading system and a plastic membrane to reduce ink backflow, and fits a broad range of rotary and coiled tattoo machines for flexible studio use.

Which needle sizes are included and why that mix matters?

This set contains 50 cartridges across five #12 round liner configurations, giving you a graduated selection from tighter to wider groupings. The assortment covers many typical outlining and detailing needs so you can switch quickly between fine and bold lines during a session.

• 10 x 1203RL — tighter group for fine lines and detail
• 10 x 1205RL — small-liner for hairlines and small scripts
• 10 x 1207RL — medium liner for everyday outlining
• 10 x 1209RL — wider grouping for solid outlines and shading edges
• 10 x 1211RL — bold liner for thicker outlines and graphic work

How do these cartridges prevent ink backflow and contamination?

Each BIGWASP cartridge includes an internal plastic membrane and uses a rubber-band loading mechanism to help stop ink from traveling back into the tube. Additionally, individual sterile sealing preserves cleanliness until the moment you open a cartridge.

• Plastic membrane reduces ink siphoning into the grip
• Rubber-band loading keeps needles stable during use
• Individually sealed packs maintain sterility before use

Will these cartridges fit my machine and work with my inks?

These #12 RL cartridges are built to be broadly compatible: they snap into most rotary and coiled machines as well as Hawk-style grips. They accept common tattoo inks and fluids used in professional studios.

• Compatible with rotary, coiled, and Hawk machines

• Works with typical water- or alcohol-based tattoo inks
