Dry-erase crayons are the perfect way to replace the mess and smell of traditional dry-erase markers as well as relieving the danger of dry-out because someone forgot to replace the cap. Washable crayons are designed to work with your dry-erase board to deliver vibrant color. Erase cleanly from wipe-off surfaces and wash cleanly from hands and clothes. Crayons are great for children because they have no odor and no caps to lose. Washable crayons are certified AP nontoxic. Classpack includes eight classic colors: red, blue, green, yellow, orange, violet, black and brown.
