Sharpie Gel Promotional Highlighter by Pinnacle Promotions This promotional highlighter sets itself apart from other highlighters for many reasons. For one, the unique gel link won't bleed through paper, no matter how thin. There is also strong smear protection, so you won't end up with neon hands. Finally, the ink will never dry out and then pen will last as long as a traditional pen-style highlighter. The Sharpie Gel Promotional Highlighter is available in five different colors with your logo nicely printed on the barrel.
