An important tool for studying, notetaking, and any job where large amounts of text need points of emphasis, highlighters are an essential item in any desk drawer. Highlighters use a translucent ink to add color and emphasis to text without writing over or smudging the text itself. OfficeSupply.com carries several types of highlighers. Tank-style highlighters feature large barrels and ink reservoirs, while pen-style highlighters are easy to grip and control, allowing for more precise highlighting. Also find erasable and refillable highlighters to get more out of your marker.
