Free Key
Someone decided to redesign the key ring we’ve been using for eternity. It’s called FreeKey:
Save your nails–the Free Key key ring makes it incredibly easy to put keys on without having to worry about prying the rings apart with your fingernails. The Free Key is designed in such a way so that you can press down on the opposite end of the ring and have the opening lift up without much effort.
