Sterling Kauai Hawaii Enamel Charm Vintage NOS on Card

Great vintage sterling silver and enamel Kauai Hawaii charm. Never used and still attached to the original cardboard card. It's marked Sterling Silver on the card and Sterling on back of the charm. The charm measures about 3/4" high including the ring at top and it's in great vintage condition with just some light tarnish. The card has some discolored lines on back.
