Crayola Color Cycle is a program that allows markers (of any kind or brand) to be recycled and reused. All we have to do is a school is simply be signed up and once we fill up a box and know the weight, we print out a shipping label (provided free by the Crayola website). Then, we simply send the markers back. I believe for every 250 markers we send we get a new free pack as well. With that being said, if you have any markers at home that could be recycled... send them to school!
