Gel HighlighterFeatures gel stick technology, which provides the strongest smear protection across pen and marker inks and inkjet printouts. Won't dry out if left uncapped, or bleed through paper. Works great on all paper surfaces, including glossy or thin papers. Conforms to your handwriting style and writes as long as a traditional pen-style highlighter. Twist bottom to advance gel stick.
