Create splashes, drips, spray effects, and more with Posca Mop’r Paint Markers. These ergonomic, semi-rigid markers have a foam rubber tip and barrel design that allows for generous applications of color. Create horizontally or vertically, holding the marker right-side up for fine details or upside down for a higher ink flow. The water-based paint is odorless, rich in natural pigments, and gives you dense, vivid colors.
