This Posca marker has a brush tip that creates sweeping brush strokes and stylish lettering. It's excellent for illustrations, signage, decorating or labeling items, and other art projects. The tip consists of synthetic bristles. Uni Posca paint markers use vivid, opaque ink that can write on virtually any surface, including paper, photos, glass, wood, plastic, and metal. The paint ink can be scraped off from nonporous surfaces like glass but adheres permanently to porous surfaces like paper. It shows up well on both light and dark surfaces, and once dry you can write over it with another Posca marker without smearing or showing through. The ink is a water-based pigment ink, and is non-toxic, lightfast, and waterproof. To start using the marker, shake it with the cap on so that the ball inside rattles. Then remove the clear cap at the top of the pen, and uncap the pen tip. With the tip pointing down over a piece of scratch paper, press the black button at the top a few times until ink flows into the brush tip
