2 pack
Good thing this was a 2-pack, because the first one broke within 1 week. One of the little balls that keeps the 2 parts together came out and they no longer lock. I was afraid of that as I've seen these keyrings before and experienced that very same problem. The other one seems to be holding up for now, but I don't expect it to last forever. For the price, it's ok.
