You know you're hooked when your key chains match. These little key rings, complete with a weighty Ball and Chain and a neat handcuff locking mechanism, are a daily reminder that you're well and truly attached. Getting your keys and assorted key chain paraphernalia on and off them is much easier than with those irritating split ring gadgets, as the handcuff clip snaps open and shut securely at the click of a subtle little switch. If only it was that easy to attach and un-attach yourself to people?
