Non-toxic, water-based POSCA paint markers can be used on almost any surface, and are loved by professionals, creative hobbyists and amateurs alike. The alcohol and solvent-free opaque paint covers well, is blendable, dries quickly and can be overlaid when dry. ACMI certified and made in Japan. The PC-17K extra-broad, rectangular chisel tip marker is a favorite of professionals and artists for creating large-scale artwork. Great for filling in background colors, wall murals, urban art, interior design and more.
