Kwadron Cartridges - Empty Round Liner 0.35mm Long Taper, Box of 20

Clean, consistent line work starts with a cartridge you can trust not to wobble mid-session. The Kwadron Cartridge System in 0.35 mm Empty Round Liner Long Taper gives professional tattoo artists a reliable, sharp needle platform built for heavy outlines, bold lettering, and solid colour packing. Each cartridge is EO gas sterilised and single-use disposable, keeping your station hygienic from first client to last.

The built-in needle stabilising system locks the needle grouping firmly in place, eliminating chatter and helping you lay down precise, blow-out-free lines pass after pass. A medical-grade plastic housing minimises friction between needle and tip, so sharpness holds up across a full session rather than degrading as you work.

A safety membrane provides back-flow protection, preventing ink from travelling into the grip or machine body. The long taper configuration offers finer, more precise line entry compared to a medium taper, making it the stronger choice when sharp, clean lines are the priority. The cartridges use a standard fitting compatible with a wide range of tattoo machine brands.

Please select the needle count you require.
