Everyone I show them to wants to keep them.
I now -must- find a key-wind pocket watch ($).

This set of keys is the ultimate people magnet. Take them from your pocket and even total strangers are asking to see and hold them. I might have to buy a second set just to make sure I still have some when I actually find a watch to wind. :)

Well made keys that are visually attractive and are actually useful for a real-world task, total win!
