The Uni Propus Window Color Double-Sided Highlighters offer a truly unique design element. Their broad (4 mm) tips have a transparent window that allows you to see what you’re highlighting. They also feature a fine (0.6 mm) tip for highlighting small detail. The highlighters come in a slimline pen-body design and feature sturdy pocket clips. 

The Propus highlighter is more gentle on the eye than traditional fluorescent highlighters. The understated colours are a pleasure to use for study and bullet journaling. The 5 colour set includes Smoke Red, Smoke Orange, Smoke Green, Smoke Blue and Smoke Grey.
