No more changing pens for whiteboards and flip charts! Easily wipeable from smooth, non-porous surfaces, whether dry or wet (not for use on glass surfaces). It is just as easy to use as a colored pencil. Thanks to its core, this marker never dries out and ensures an intense, even color delivery until the very last stroke. The color does not bleed and does not penetrate the paper. The pen is solvent-free, odorless, and made from 100% PEFC-certified wood. A true alternative to traditional liquid ink markers.
