The Batman Cork Bi-Fold Wallet is probably made from all of those left over wine bottles from Wayne Manor. Bah, who am I kidding...everybody knows the Dark Knight only drinks his wine from boxes. He's super classy like that. Made from cork with a polyester lining, the Batman Cork Bi-Fold Wallet measures 4.5 inches across and has your standard compliment of pockets and sleeves for money/cards/coupons for boxed wine.
