Uni Posca Markers use water-based pigment ink to produce poster-like vibrant colours. Completely odour-less, light-fast and water-resistant. Great for use in the home, workplace or for the artist, they are also non-toxic making them ideal for use in schools. Non alcohol-based so the ink won’t bleed through the paper. Writes on porous surfaces such as paper, photographs, fabrics and wood but can be easily removed from non-absorbent surfaces such as glass, ceramics and plastic making them ideal for temporary signs on windows and windscreens. This pen has an acrylic chisel-shaped nib. Price per pen.
