Sharpie produces yet another technological breakthrough with the Sharpie Gel Highlighter. The advanced gel highlighting system won’t bleed through paper surfaces, including glossy and thin papers, and it provides our strongest smear protection across pen and marker inks and ink jet printouts. Uncap what’s inside without worry – the Sharpie Gel Highlighter will never dry out – and it writes as long as a traditional pen-style highlighter.
