The single sided 4.5'' inch tall Batman Crest Wallet is for you Bat-fans that don't have enough time to mess around with some nimbly-pimbly bi-fold wallet! This bad mama-jamma has a raised metal Bat symbol on one side as well as spots for cards while the reverse side has a clear sleeve for IDs. Oh, and of course you can open the polyester/polyurethane Batman Crest Wallet up...if you are still one of those people carrying around real money.
