Exotac FreeKey System
I hate putting new keys on my key ring and I bet you do too. Unless you have the Freekey System from Exotac, which makes adding or removing keys from your key ring a breeze.
Its clever design allows you to open the mouth of the keyring with a simple push rather than having to pry it open. Its an incredibly simple yet extremely function concept. By pressing the bend in the ring it opened the mouth of the ring so you can simply slide in or remove a key. Once released it closes tight.
The Freekey System comes with the main ring plus 3 accessory rings where you hang your keys.
