Kwadron Tattoo Cartridges - Round Liner, Box of 20

The Kwadron All Round Liner Cartridges help tattoo artists achieve consistent, clean linework with every session. Each cartridge houses precision-grouped long taper needles built for fine lines, contours, and detailed outlines. Sold in boxes of 20 and manufactured to tight tolerances, they deliver repeatable results you can count on.

The needles are made from surgical stainless steel and sit inside medical-grade plastic tips, keeping friction low so they stay sharp throughout your session. A built-in safety membrane prevents ink backflow, delivering consistent ink flow without flooding or drying out mid-tattoo.

A needle stabilising system holds each needle firmly in place, eliminating wobble during fast passes and tight detail work. Available in #8 (0.25 mm) and #12 (0.35 mm) diameters with a 7 mm long taper, they suit fine script, lettering, and bold traditional outlines.

Please select the needle size, diameter and taper length you require.
