SWMBO is a manager for Tiffany & Co, and yesterday they had an event in the store. One of the Tiffany master engravers was in the store and doing work on site. SWMBO was a sweetheart and got me a beautiful keyring like this one: She had it engraved with my initials and it looks great. The trouble is, I can't seem to figure out the secret to putting my keys on it! I unscrew the ball end and go to put on my keys, but a couple of my keys are too small to fit. The ring is too thick to go through the hole in the key. Am I missing something here? It there a trick?
