Japanese Uni brings a spark of innovation into the world of highlighters with their Propus Window Highlighter set. What makes this highlighter special is the transparent window on its tip which allows you to see what part of text you are highlighting. Moreover, the highlighters are double-sided and include a finer tip too. This set includes fantastic primary colors that don't bleed through the page and aren't shockingly bright.
Each set contains 5 colors: pink, orange, yellow, green and blue.
