Space-money. Is there such a thing? If there is, then you probably want the Green Lantern Symbol on Black Bi-Fold Wallet. It's probably qualified for handling that sort of thing if my experiences with the Green Lantern Corps have any meaning. I think those guys can just use their Power Rings as a debit card!Made from canvas, this thin wallet has plenty of spots for cards and money, a clear ID sleeve for government(or intergalactic) forms of identification, and of course the always required Green Lantern symbol!
