Sanford Professional Chisel Tip Markers

Sharpie Professional ink is permanent on most hard-to-mark surfaces such as wet and oily surfaces, sandpaper, concrete, brick, glass, metal, plastic, wood, sporting equipment and much more. The stronger Sharpie Professional chisel tip lasts 50 percent longer than standard chisel tips. The rubberized barrel and cap design make the cap easy to remove even when wearing gloves.
