筆、鉛筆與麥克筆零廢棄盒 - TerraCycle，回收盒

I was skeptical about shipping off a box of dried-out markers and chewed pencils, but the process was straightforward and the box itself is sturdy enough to hold everything without leaking. It's a small price to pay for keeping all that plastic out of a landfill, and I already filled my first one.
