uni‑ball Posca MOPR PCM‑22 Multicolor Surface Paint Marker, Black Ink, Pack of 1 is a versatile, high-quality paint marker designed for creative expression on a wide variety of surfaces. It features an XXL round tip (approx. 3–19 mm) that lets you produce everything from bold, sweeping strokes and fills to controlled drips, splatters, and expressive marks, making it ideal for street art, murals, DIY projects, and large-format illustrations. The marker uses opaque, water-based pigment ink that is non-toxic, quick-drying, and lightfast, offering strong UV resistance and vibrant coverage on porous materials like paper, wood, and fabric, while also being removable from many smooth non-porous surfaces. The ergonomic, squeezable barrel and reversible, washable tip enhance flow control and creative flexibility, so you can work intuitively at different angles and effects.
