These wallets fold up in an accordion type fold. The front is half of a cassette, the back is the other half, and a wide strap wraps around the entire wallet and fastens to the front. When unfolded: There is a slot for bills and a slot for a credit card or driver's license. And of course, the Crash Landing label.
Wallets range from $15.00 to $20.00 If you are ordering one, let me know what kind of music you like :)
