Combining the benefits of fine illustration pens with the versatility of the POSCA range, the PC-1MR features a calibrated tip that produces a consistent, reliable 0.7mm line. Incredibly versatile thanks to their acid-free, richly pigmented & uniquely opaque water-based paint, POSCA markers are fully intermixable when wet & quickly dry to a clean, matt water-resistant finish that can be varnished, layered and more. Made using acrylic or plastic for robust applications, their wear-resistant tips are hardwearing enough to produce bold, beautiful artwork on almost any surface including paper, card, wood, stone, glass, metal, wood & fabric. Similar to a traditional aerosol can, each marker includes a small internal ball in their barrel which, when shaken vigorously, effectively mixes the paint itself.
