Uni Posca water-based pigment markers produce opaque, vibrant color 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 odorless, 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 Posca PC-8K has a broad chisel tip which is 8mm wide. It can be used for bold marking in any artistic situation, though it is particularly well suited to flat tints, street art, signage, and covering large surfaces.
