The Uni-Carts Round Shader shades where the big mags can’t reach. A round needle grouping lets you work soft shading, small colour fills and tight corners with total control — and pull sculpted, softer lines when you want them.
Like every Uni-Carts cartridge, it runs the patented stabiliser system and strengthened membrane for a smooth, consistent hit. Bugpin 0.30 mm sizes give finer, more gradual shading; 0.35 mm standards build saturation faster for richer fills.
- Patented stabiliser system for a steady, judder-free hit
- Strengthened safety membrane to help prevent back-flow
- Each needle inspected by eye for a clean, sharp point
- Universal fit with all standard cartridge machines and grips
- Single-use; supplied in boxes of 20
Choose your size: e.g. 1207 = 0.35 mm, 7-needle round shader. Ideal for soft shading, whip shading, small colour packing, detail fills and softer linework.
