This POSCA paint marker set can be used to decorate almost any surface you can dream up: paper, glass, cardboard, wood, porcelain, metal, textiles, ceramics, plastic, and much more. These "multi-purpose," fade-resistant markers produce neat and precise lines with beautiful colors, resulting in stunning effects for your indoor and outdoor projects. The alcohol- and solvent-free opaque paint is not only blendable but also covers surfaces well, dries quickly, and can be layered once dry. It is permanent on porous surfaces and erasable on most non-porous surfaces. Ideal for beginners and professionals alike, these versatile markers are perfect for arts and crafts, coloring, line drawing, and ornamentation. The marker tips can be rinsed with water to keep them intact, allowing you to dilute, mix, and blend without fear of ruining your marker.
