1950s Vintage Coasters resin shells made in USA 🇺🇸 by Unique Designs(set of 4)

These belonged to my grandparents who owned a grapefruit grove in Florida in the 1950s. They have been packed away in a China cupboard. Time to rehome. They are still in the original box, which has quite a bit of wear due to age, but the coasters are in very good condition. Made in the USA. A great slice of 1950s americana. Fragrance and smoke free. Resin with sliced shells. Each one is a “unique“ design. Duh, that’s the name of the company!
