POSCA markers use water-based paint with stable pigments that can be applied to all materials. POSCA paint is permanent on porous surfaces, such as wood, cardboard, and textiles, and removable on smooth, non-porous surfaces, such as glass, plastic or metal. Depending on the surface, there are ways to optimize permanence including: applying a varnish; baking in the oven; ironing the surface; or adding a fixative to prevent dust or damage over time. You can read more about the use of POSCA markers on various surfaces on the page above.
