Avery Marks A Lot Permanent Marker 07888, Black Ink, Chisel Tip, 4-7/8". Marks-A-Lot permanent markers make it easy to leave your mark. Durable chisel tip does not fray over time and makes it easy to create lines in various widths and sizes. This remarkable, permanent marker ink sets in quickly when written, but won't become dried out if you forget the cap. Leave the cap off the marker for up to 30 minutes, and you'll still be able to pick it back up and keep writing. Versatile permanent ink resists wear, fading and water exposure. These low-odor markers work on almost all surfaces including paper, cardboard, metal, PVC pipes, concrete walls, plastic and ceramic. They are great for marking sports equipment, creating yard sale signs and marking boxes in warehouses. Marks-A-Lot permanent markers cover every use for classrooms, offices, manufacturing facilities and more. Ink is ACMI certified as nontoxic and conforms to ASTM D4236.
