KeyKlip Carabiner Key Holder
We've seen plenty of foldaway keychains before, but I like the KeyKlip's rugged, flat plate design and carabiner edge to some of the longer and narrower versions. The basic KeyKlip has an interior KeyDisk that holds up to 10 keys, and expanders are available if you want to load more. All hardware for keying in is included, as is a key fob holder you can also use as a bottle opener.
KeyKlips come in colors Gunmetal and Onyx.
