Batmerican Express; never leave home without it...or the fantastic 3.5'' by 6.5'' Batman Symbol Checkbook Wallet! I think something like that what down in that 'Batman and Robin' memory but my survivor's guilt keeps me from wholly recognizing that entire movie. Made from a combination of polyester and polyurethane, the Batman Symbol Checkbook Wallet is a triple fold wallet with tons of space for all sorts of things!
