Uni Posca

Uni Posca is one of the world’s most recognisable marker brands, trusted by artists, designers and hobbyists since its introduction in Japan during the 1980s. Manufactured by Mitsubishi Pencil Co., Posca markers use a water-based pigment ink that is both vibrant and opaque, making them suitable for use on almost any surface including paper, wood, glass, plastic, metal, stone and fabric. Known for their smooth application, strong colour payoff and quick drying properties, Uni Posca markers have become an essential tool for creative expression across art, design and craft communities worldwide.

Markers and Creative Tools

Uni Posca markers are available in a wide range of nib sizes, from ultra-fine tips for detailed line work to broad chisels and bullet tips for bold fills and coverage. With an extensive colour palette, including metallics and pastels, Posca markers allow artists to layer, blend and customise their work with precision. The water-based ink is permanent on porous surfaces, removable on non-porous surfaces, and can be fixed with heat on textiles. This versatility has made Posca a go-to choice for both professional artists and casual creators.
