Perfect for those situations when you need to be bold, big and brilliant, this jumbo marker is the largest Avery Marks A Lot marker available. The durable chisel tip is 5/8" wide and can be angled to write lines in multiple widths without fraying over time. This remarkable black 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. The versatile permanent ink resists wear, fading and water exposure and works in almost any situation. These markers work on numerous surfaces including paper, cardboard, metal, PVC pipes, concrete walls, plastic and ceramic. 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. Avery Marks A Lot markers are non-toxic and low-odor. Our ink is ACMI certified as non-toxic and conforms to ASTM D4236.
