PLEASE NOTE: This item has been discontinued by Dixon and we have sold out of our stock. We are trying to see if they will make a special run for us so we can get them back in stock. This may not be possible. In the meantime, we are offering the following option on our parent website, CSP Outdoors. Many of our customers have used them and say they work as well as - if not better - the Vis-Aid Markers. They also come in other colors. We are now offering an alternative product, the Staedtler® Lumocolor Omnichrome Marking Pencil. Black graphite writing core is ideal for paper, plastic, photos, X-ray plates, glass and other slick surfaces. Won't scratch the marking surface and can be removed easily with a damp cloth. Ideal for film editors and X-ray technicians. PMA certified non-toxic. Packed 12 to a box. Made in the U.S.A. Dixon Vis-Aid Film Marker 12225$10.95 Need more information?
