We were first attracted to the looks of the Matt and Nat bags--then liked them even more once we learned the vegan bags feature linings made of recycled bottles. The lining of each bag is stamped to let you know exactly how many bottles were used, for example, 16 recycled bottles were used for the above bag.
If candy wrappers are more your thing, consider the Nahu Ollin line of bags that are made of recycled wrappers by small communities in Mexico.
Or check ot this Harvey Treecycle Wallet, made of recycled seatbelts.
