This is a vintage joke cigarette pack. Made by J. Chein & Company. Labeled "Camals", a VERY close approximation of Camel cigarettes. You use a key to wind up a spring, lay the pack on a tabel, and when you pick it up, it vibrates.
I have found a few completed listings on Ebay. But sold prices vary. Curious if this is in a price guide somewhere.
