Uni Propus Window Double-Sided Highlighters

The Uni Propus Window Highlighters are double sided with one side for highlighting lines and the other for circling, writing, or finely drawn diagrams. The thin, marker side is 0.6mm. The highlighting side is 4.0mm thick and has a window in the tip of the nib, so you can see where to start and stop highlighting a line. The window allows for increased accuracy when highlighting. These highlighters are in vibrant, neon colors: pink, orange, yellow, green, and blue. Each highlighter is 13.8 cm or 5.4 inches long when capped.
