Posca Paint Markers provide very rich, opaque pigments. Its unique water-based formulation delivers bright, matte, opaque colours that withstand the passage of time. It has no odour. Layerable, mixable, water-soluble, weather-resistant, no fewer than 55 colours (some with glitter, metallic or fluorescent) offering unlimited creative possibilities. To ensure a consistent texture from beginning to end, a little ball is placed inside the marker to mix the ingredients of the POSCA paint. Just shake the marker energetically (with the cap on), and you will hear its characteristic, sought-after clicking!
