Every pad needs a pen. Every whiteboard needs slick writing tools. Write, chart and brainstorm on any non-porous whiteboard surface. The Global Industrial™ Dry Erase Marker and Eraser Kit contains one single eraser for making quick corrections or clearing board space, and a mix of primary and secondary colored markers to help bring a more vibrancy to your presentation. Dry erase markers are the perfect writing tool on non-porous surfaces because of the oily polymer material in the ink that doesn't dry instantly on surfaces. Each marker is thick pointed with a bullet tip.
