Two colour-tips in one pen! The new JOLLY highlighter promises double-fluorescence – now marking books, notes and various office- or school supplies become colourful spectacles! The high-quality, non-toxic universal ink (water-based) dries within a few seconds. The colours can also be easily washed out of clothing. Double-colour-effect: Use both colours at the same time and highlight very important information in your notes even more colourfully!
