The POSCA Ultra Fine Paint Marker can be used on almost any surface you can dream up like paper, glass, cardboard, wood, porcelain, metal, textiles, ceramics, plastic and much more. Its alcohol and solvent-free opaque paint covers surfaces well, is blendable, dries quickly and can be layered when dry. The PC-1MR ultra-fine tip has the same qualities as a paint marker in the form of a fine tip pen, and is designed for those requiring an ultra-fine and consistent line. This market is a favorite of both children and adults to color or write with accuracy. It is ideal for all ages, from preschool to professional, and is a fluid and fun choice for art, craft, graffiti or decor. The tips can be rinsed with water to keep marker intact, allowing you to blend without fear of ruining your marker.
