Uni POSCA Paint Markers were introduced to the Japanese market in 1983 by Mitsubishi Pencil Co., an innovative manufacturer that had already expanded well beyond its original business of making wood-cased pencils. Like Mitsubishi's other Uni brand products, POSCA quickly swept into shops, offices, and studios worldwide, thanks to its non-toxic, opaque ink that covers and flows like paint—but eliminates the mess, odor, and inconvenient application of other paint markers. POSCA works on pretty much any surface, from paper to metal, so you can use it for art, craft projects, addressing envelopes, marking your name on your lunch, and quite a bit more. These brightly colored markers are popular with graffiti artists and mixed-media painters, schoolteachers and calligraphers. POSCA paint is permanent on porous surfaces like paper and wood, and removable with Windex from non-porous surfaces like glass and metal. This is the POSCA PC-3M, with a fine rounded felt tip that makes neat lines from 0.9 to 1.3 mm, depending on your pressure and writing angle. It's great for drawing, household use, and decorating windows and chalkboards, and it comes in a huge range of color choices. Sold individually—choose your color from the dropdown menu. Also available in a variety of other sizes and shapes. Made in Japan.
