In a world where plastic is taking the place of cash, you probably don't need one of those thick wallets anyway. Think about it this way: With the Magic Wallet, if you get a business card, a receipt, or a phone number scrawled drunkenly on a piece of paper, you can place it inside your wallet without worrying about losing it in your pockets or having it fall into the abyss of a cab's back seat.
The only drawback, however, is that now you'll have to remember to take that stuff out of your wallet. Otherwise, the wallet will quickly feel far less magical.
