"We’ve seen bike parts get turned into a variety of different things, but we’ve never seen something from a bicycle get turned into an item as simple and sharp as this keyring. Crafted from an old bicycle spoke, this minimalist key holster is basic but brilliant. Just unscrew the top to add keys and you’ll be giving new life to a fallen ride." -coolmaterial
