Uni Posca water-based pigment markers produce opaque, vibrant colour and will on write on virtually any surface: paper, cardboard, tracing paper, rock, clay, cement, plastic, metal, wood, fabric, glass, canvas and more. These markers are odourless, alcohol- and solvent-free, and suitable for indoor or outdoor use.

Posca paint is opaque and fluid. It gives easy coverage and yet is bleed-resistant when used on paper. Once dry, the paint is waterproof; it is possible to draw on top of previous layers to build up designs or correct errors. Light colours are just as opaque as the dark colours, and can be used to add overlaid highlights.

The PC-17K is the largest member of the Posca range. It has an extra-broad chisel tip of 15mm width
