From wine bottles to illegal baseball bats, cork has often been a material you put in other items. Now, you can put something in cork, namely your cash, credit cards and pieces of identification. Jack Spade takes the oft-underused product and utilizes it to make the Cork Billfold and Cork Flat Wallet. While these little carry-alls look subtly stylish, they’re also quite smart. Cork is extremely durable and flexible, two features that come in handy when you’re jamming, say, another receipt in there, George Costanza. Plus, cork is also water resistant so you don’t have to be fearful of ruining your investment and the money you’d use to buy a new one in the process.
