POSCA paint markers are an excellent multi-surface, creative pen. The uni POSCA chunky chisel tip paint marker contains water-based pigment ink which is lightfast, water-resistant, and will write on almost any surface. The PC-8K 8mm broad chisel tip draws neat curves and covers large surfaces in a wide range of colours. A Street Art’ favourite, it is also fantastic for large italic-style hand-writing and large format work.
