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. The paint dries very quickly, especially on porous surfaces; simply wait a few minutes and the paint will be dry. Posca paint is permanent on porous surfaces, and removable on non-porous surfaces such as glass. This makes them perfect for temporary signage and window art.

These markers are odourless, alcohol- and solvent-free, and suitable for indoor or outdoor use. They are widely used within the artistic community for sketching out large projects (such as murals) and even signing finished work. Before use, please shake the marker vigorously with the cap securely attached in order to move the mixing ball within the barrel. This will ensure that the paint is homogeneous and that the pigments are fully suspended. On a test sheet, press down the tip several times to start the paint flowing.

Posca paint is opaque and fluid. It gives easy coverage and yet is bleed-resistant when used on paper. While the paint is wet, other Posca colors can be applied and blended on the surface, or water applied for a diluted watercolor-style wash effect. Once dry, the paint is waterproof, lightfast and non-bleed; it is possible to draw on top of previous layers to build up designs or correct errors. Light colors are just as opaque as the dark colors, and can be used to add overlaid highlights.

Using Posca Markers on ceramic

Posca pens are suitable for creative works on ceramic/porcelain. Once baked in the oven, they will become permanent. If you want to keep a POSCA artwork made in ceramic or porcelain, it is recommended that you use a matte lacquer hair spray or slow cooking up to 120 °. Wash in cold water only.
