Desk set with 15 different colours of Stabilo Boss Original Highlighters. Water-based and quick-drying highlighters that are comfortable to hold. We like using them to fill out simple graffiti sketches but of course, they are also perfect for highlighting text in books. Stabilo has developed an “Anti-Dry” technology which makes it possible to leave the highlighters with the cap off for up to four hours without them drying out.
