The Uni-Carts Straight Magnum is your workhorse for big areas. A flat row of needles lays down colour fast and even, making it the go-to for solid colour packing, saturation and large fills.
The patented stabiliser system holds the whole row level so it deposits consistently, pass after pass, while the strengthened membrane helps keep your machine clean. Bugpin diameters (0.25 mm / 0.30 mm) suit smoother, more controlled work; 0.35 mm standards pack bold, saturated colour quickly.
- Patented stabiliser system for a level, judder-free row
- Strengthened safety membrane to help prevent back-flow
- Each needle inspected by eye for build quality
- Universal fit with all standard cartridge machines and grips
- Single-use; supplied in boxes of 20
Choose your size: e.g. 1215 = 0.35 mm, 15-needle straight magnum. Ideal for colour packing, solid fills, large-area shading and bold work.
