Kwadron Liners Cartridges

Kwadron Liners Cartridges are Round Liner (RL) tattoo cartridges built for artists who want clean, single-pass lines. The needles are grouped in a circular configuration, which delivers strong ink flow and precise control, from fine linework to bold outlines. A safety membrane prevents ink backflow into the machine, and the cartridges are EO gas sterilized and sold in boxes of 20.

What you get

• Box of 20 cartridges
• Diameters: 0.25 mm (#08), 0.30 mm (#10) and 0.35 mm (#12)
• RL LT (Long Taper): softer entry and more precision, ideal for fine lines and detail work, in 0.25, 0.30 and 0.35 mm
• RL MT (Medium Taper): more skin contact and stronger saturation for bold lining and traditional work, in 0.35 mm
• RL LT Turbo: long taper with textured needles for enhanced ink flow, in 0.35 mm
• PMU Optima: permanent makeup cartridges in 0.20 and 0.25 mm
• Needle counts from 1 to 18 depending on the configuration: 1, 3, 5, 7, 9, 10, 11, 13, 14, 15 and 18

Reach for a 1 or 3 RL for script and fine detail, 5 to 9 for standard outlines, and 11 to 18 when you need heavier lines or want to fill small areas quickly. The long taper gives a gentler entry for delicate work, while the medium taper pushes more pigment for saturated traditional lines. Round liners are usually paired with magnum or shader cartridges so you can run a consistent setup from outline to fill.
