If you're cleaning out that old school supplies making room for the new stuff, don't let those dried up markers go into a landfill- send the to Crayola!
Crayola's ColorCycle program wants schools to send them any and all brands of old plastic markers and they will recycle or re-purpose them! They'll even send a shipping label, so you don't have to pay shipping!
Currently, this program is only open to schools... so if you have some markers to recycle then ask your school to get on board! Visit Crayola's website for more info!
