These highlighters are packed with useful and innovative features. Their water-based, pigmented "Q-Dry" ink dries in one third the time of a typical highlighter, minimizing the chance of smudging on hands and paper—even on semi-glossy textbook pages!
Their versatile, double-sided design incorporates a broad, 4 mm windowed chisel tip for highlighting blocks of text on one end and a fine, 0.6 mm tip for writing and underlining on the other end.
The windowed chisel tips let you see ahead of where you're highlighting so that you can stop highlighting exactly where you want to.
