The Uni-Carts Round Liner is built for one thing: lines you can trust. Each cartridge runs our patented stabiliser system and a strengthened membrane, so the needle hits the same spot every time — no judder, no wandering, just crisp outlines, tight detail and clean lettering.
Round liners group the needles in a tight circular cluster for precise, confident linework. Smaller diameters (0.25 mm and 0.30 mm “bugpin”) give you finer, more controlled lines for delicate detail; the standard 0.35 mm sizes lay down bolder outlines. Need maximum ink in a single pass? The hollow liners have an open centre that carries more ink for bold, free-flowing lines with fewer passes.
- Patented stabiliser system — eliminates needle play for steady, repeatable lines
- Strengthened safety membrane — helps prevent ink and fluid back-flow into your machine
- Each needle inspected by eye for a sharp, consistent point
- Universal fit — works with all standard cartridge machines and grips
- Single-use for hygiene; supplied in boxes of 20
Choose your size: codes read as diameter + needle count — e.g. 1207 = 0.35 mm, 7-needle round liner; 1009 = 0.30 mm bugpin, 9-needle. Ideal for outlines, fine line, script, geometric work and detail.
