The one size fits most Batman Wrap Around Rubber Wristband should probably be a part of the Utility Belt setup though I'm not entirely sure what the Caped Crusader would use them for...or you for that matter! Well, I guess you can just wear this thing to show off your Bat-Pride but you might need to test your resourcefulness to come up with something a bit more practical. I could be talking to the Dark Knight right now and you've already come up with something to do with the Batman Wrap Around Rubber Wristband!
