The Uni-Carts Soft Edge Magnum is our softest-shading cartridge — engineered to feather ink right at the edges of the row for whisper-smooth gradients and seamless black & grey. Where a standard magnum can leave a defined edge, the Soft Edge melts tone into skin with no hard lines.
It carries the full Uni-Carts build: the patented stabiliser system for a flawless, judder-free hit, a strengthened membrane, and needles inspected by eye for the sharpest, strongest point. This is the mag you fit when the blend has to be perfect.
- Feathered soft edge — the smoothest gradients and blends in the range
- Patented stabiliser system for a flawless, consistent hit
- Strengthened safety membrane to help prevent back-flow
- Each needle hand-inspected for superior build quality
- Universal fit; single-use; supplied in boxes of 20
Choose your size: e.g. 1215 = 0.35 mm, 15-needle soft edge magnum; bugpin options give the most gradual shading of all. Ideal for black & grey realism, portraits, soft colour blends and finishing.
