POSCA is a paint marker popular with artists and creative hobbyists. An essential tool for creation and self-expression, it is used by amateurs and professionals every day on all types of materials. Most POSCA tips are washable and replaceable (PC-1MC, PC-3M, PC-5m, PC-7M, PC-8K and PC-17K). Some are also reversible (PC-3M and PC-5M). If a tip ever dries out over time (for example if the cap was not put back on properly), you can soak it in a glass of water to be able to use it again.
