The well-defined lines that divide the functional areas of this whiteboard marker give it a clean and distinctive look. As a contribution to reducing waste and thus environmental protection, the pen can repeatedly be refilled with ink. To do this, the back cover just has to be lifted slightly and rotated. In contrast to traditional, alcohol-based ink, this marker pen uses a water-based whiteboard ink which has the advantage of not having an unpleasant or irritating odour.
