Not since Liquid Paper has there been an innovation in office supplies as awesome as this highlighter's see-through tip that makes it easier to see the text as you're... well... highlighting it.

Cooked up by the Mitsubishi Pencil Company—which sounds like it would have an awesome factory tour—the cheap $1.60 Uni Promark View uses a thinned water-based pigment ink that flows down a channel inside the highlighter's clear plastic tip. The design provides a window so that you can always see the text you're highlighting, and don't accidentally overshoot the end of a sentence. Technically it's not a problem that's ever really cost someone a passing grade, but that doesn't mean it wasn't worth solving.
