The Soft Edge Magnum Long Taper in 0.30mm (#10) is a curved magnum: the curved needle arrangement produces what is known as a haze when shading, with fuller colour in the centre and a soft falloff at the edges. Colours blend into each other without a hard colour edge, so the borders of your image seem to fade into the skin rather than sit outlined on it.
That makes this magnum ideal for soft shading, blurred backgrounds, bokeh style effects and smooth transitions in portraits and realism, as well as for packing black or colour. The 0.30mm size lays colour into the skin smoothly and gives gentler transitions between black and grey than the 0.35mm, with less trauma to the skin. Kwadron's needle stabilisation system keeps the configuration stable through the whole session.
This magnum ships in boxes of 20 individually sterile packed cartridges, and every cartridge carries the original Kwadron code so configuration and size are always readable at a glance.
