If you’ve spent a lot of time on two wheels, you might recognize that this keyring is made from used bike spokes. Just screw/unscrew the spoke nipple to add or remove keys; it’s as simple as that. And don’t go thinking you have to be a bicycle nut to have one of these- the simple reuse of a spoke is reason enough to consider it for your everyday keys. Available from scene3.
