With a capless, click-and-go design, the Sharpie Retractable Highlighter offers on-the-go convenience for highlighting, organizing and marking up important documents. The push button makes this one-handed highlighter simple and effective, and quick-drying ink won't bleed through most paper, so you can even highlight on handwritten notes and inkjet printouts. A handy Safety Valve prevents the Sharpie Retractable from drying out, and a convenient pocket clip lets you carry it wherever you go. Each box includes 12 highlighters.
