Posca Mop'R features a round foam rubber tip and innovative barrel design for a generous application of color. With its truly ergonomic shape and semi-rigid design, it offers a new grip and a unique artistic experience. Create large drawings horizontally or vertically with the Mop'R. It can be used right side up for finer details or upside down for high link flow. Use Mop'R to create an endless variety of effects that are harder to achieve with other tips. It's perfect for creating splashes, stamps, spray effects, drips, highlights and more. Like all Posca markers, Mop'R paint is safe, water-based, mixable and colors can be over layered. Lines between 3 and 19mm can be achieved depending on the angle of the tip. The 8-Color Mop'R Set includes white, yellow, green, light blue, pink, red, black and blue.
