Carabiners make great keychains. The problem with them is that they're typically designed for use in rock climbing, or otherwise made from cheap materials. The Handgrey Carabiner is neither. Developed specifically for use as a keychain, this handsome carabiner is made solely from Grade 5 Titanium, making it light and strong. It also features a quick-release system that makes it fast and easy to add new keyrings, a stylish stone tumbled finish, and your choice of three slightly-different designs.. Whether it's hanging from a hook, bag, or beltloop, it's guaranteed to look great.
