A long sturdy key chain, this one fits the ball if you want to attach your keys to your belt and still be able to reach a mailbox at any reasonable distance or open multiple door locks, etc. For those, not I, with a somewhat daring approach to the fashion statement of the key chain it can serve the aesthetic as well functional need  for which I bought it. Not, however, for the person looking for something with some aesthetic refinement. This is a working not a fashion chain.
