Tik Keychain
We all know that bundles of keys can take up a ton of space in your pocket or bag — but if you think about it, it's not really the keys themselves that take up all the room. It's the top of the keys, and the way the are meant to sit back-to-front. The Tik Keychain rethinks this situation, placing the blades — you know, the important parts — on a bicycle chain, allowing them to fold up small and stay thin while still giving you full accessibility when it's time to open a door.
