Make no mistake, you can purchase a keychain for less than a pack of gum. But did you ever consider that, in your pursuit of thriftiness, you ended up buying something you’ll have to replace on a regular basis? Perhaps it actually makes more sense to invest in a quality one that will last a lifetime, one like any of these titanium key rings. All are crafted from Grade 5 titanium, which means they’re tougher than The Mountain with armor on. Whether you choose a Bauhaus Carabiner or the simple Knox Key Ring, you’ll have something to handle your keys for the foreseeable future.
