You know the Batman uses the 1.75 inch high by 2.5 inch wide Batman Double Sided Symbol Lucite Keychain. How couldn't he? He has a lot more than the Batmobile, that's for sure. He needs a place to put the keys for the Whirly-Bat, the Bat-Boat, the Batpod, the Bat-Segway, the Bat Jazzy, the Bat light cycle, the Bat Zeppelin, the Bat Star Destroyer, and the Bat Delorean(to counter Booster Gold). I'm not quite sure if you have such a fleet of vehicles, but I'm pretty sure you still have some keys that could use some 'Battin' up. Get the Batman Double Sided Symbol Lucite Keychain and feel the Bat-Power!
