Staples: Handy-Lines Slim Retractable Highlighters, Assorted, 4/Pack by Pentel
The last time I had to buy a highlighter the choices were few. In fact, there was no choice. Big, fat and yellow . . . or nada. Now you can have a different color for every subject. And for less than the price of a foot-long sub, you can even treat yourself to a set of these sleek pen-like versions. Highlighting at its finest.
