Make your mark on the world with Avery Marks-A-Lot permanent markers. These large, thick markers hold over 30% more ink than regular desk-style markers. The resilient bullet tip stays solid even with frequent use and is great for creating bold, clean writing. The versatile, permanent black ink dries quickly when used but won't dry out if you forget the cap. Leave the cap off for up to half an hour and you will still be able to pick the marker back up and keep writing. The permanent ink resists wear and water exposure and is perfect for any use. These markers work with multiple surfaces including paper, cardboard, metal, PVC, concrete, plastic and ceramic. Write on sports equipment, make signs for yard sales, mark boxes and more. Marks-A-Lot bullet tip markers are great everywhere from classrooms and offices to warehouses and manufacturing facilities. Avery Marks-A-Lot permanent markers are also low-odor and nontoxic so that they can be safe in classrooms as well as in laboratories. The ink is ACMI certified as nontoxic and conforms to ASTM D4236.
