Made from a combination of polyester and polyurethane, the Transformers Bi-Fold Snap Chain Wallet has the Autobot symbol on one side while the other has the symbol for the Decepticons! It is like there might be a battle at any given moment...or when you open up the Transformers Bi-Fold Snap Chain Wallet. Well, there's that battle I was talking about. At least your money won't be bored!
