Crayola recycles old markers! You collect them, register with Crayola, and the shipping is free. They send you a label to print. They take ALL markers, not only Crayola. People who purchase Crayola products can return their old, unwanted markers to the company via ColorCycle. To participate, pack your markers in a box, print a shipping label from the company’s website, and send them off via FedEx.
