A set of 4 round pastel shades of blue, pink, yellow and a bit of green with a mother of pearl finish. They are large, 1-1/8" across with a 1/8" depressed band around the edge. They are 1/4" thick including the shank. I believe they are made of bakelite and they have a Mid-Century Modern vibe. They are in good used condition with few signs of wear. First class shipping is included. All my items come from my clean, smoke free home. Multiple shipping costs are combined-any overcharge will be refunded. Message me with any questions or an offer.
