How about a keyring which ‘locks’ your keys perfectly in a bunch? Artlebedev Studio has one such keyring in store, that allows you to bundle a set of keys in a pixelated lock. If you are not interested in having a ‘lock’, you could also opt for a pixelated ‘key’. These pixelated designs are unique and are sturdy. In fact both the keyrings are fairly bendable and are made of PVC.
