Round liner cartridges keep the needles in a tight circular cluster, which is what you want for any work built on line — outlines, script, fine detail, geometric, and dot work. The tight grouping lays down a clean, defined line and holds that edge consistently whether you're pulling a long single pass or working slowly through tight detail.
This collection pulls together round liner cartridges across every brand we stock — Cheyenne, EZ, Kwadron, Bishop, Grizzly, Mast Pro and more — in gauges and needle counts from single-needle (1RL) fine-line work up through bold traditional liners (14RL and beyond). All run a safety membrane to block ink backflow and fit any standard cartridge machine.
Not sure which count you need? Lower counts (1–3RL) are for fine, delicate lines; higher counts (7–14RL) pack more ink for bold, single-pass outlines. Fast shipping across Canada from Maple Tattoo Supply.
