This is an adorable little vintage pin. It is a goldtone cocktail shaker wet with clear, blue, green and red rhinestones. It measures approximately 7/8"H and is unsigned. It could be unmarked Coro. It is in good condition. The photos are highly magnified and make the metal look dark in places and the rhinestones dull. This is not the case when seen in person.
A great little piece for a man or woman to wear to a cocktail party!
