Measuring 3.5'' by 2.25'', the Joker Credit Card Bottle Opener is a heavy duty stainless steel tool for your wallet. What does it do, exactly? Well, it doesn't open credit card bottles which is just kind of wierd and hard to come by. What is actually does is open up regular bottles but happens to be the size of a credit card! I guess syntax is important, eh? With the Joker Credit Card Bottle Opener you'll have a versatile instrument worthy of Batman's utility belt. I don't think if the Joker quite appreciates that or even Batman for that matter but at least we can agree that the Joker Credit Card Bottle Opener is super cool!
