If your favourite POSCA marker has dried out, you don't have to throw the whole thing away — just replace the tip! The PCR-3 set contains 3 replacement tips for the POSCA 3M acrylic marker. Thanks to its high-quality ink, this opaque marker is also suitable for dark surfaces. The colours can be layered, making them suitable for painting on stones, wood, textile, metal, paper/card, plastic, glass and ceramics. Suitable for indoor and outdoor use. Waterproof once dry.
