Ecoist makes "one of a kind" handbags of varying sizes out of candy wrappers, food packages and soft drink labels. Keep them out of landfills, the argument goes, by wearing them on your arm. In addition, Ecoist will plant a tree (via Global Releaf ) for every bag purchased.
To be honest, I find them a bit on the ugly side, but Josh Rubin: Cool Hunting likes them, so what do I know?
