Wild Seas! I always try to get a calm beach scene and end up with a port hole view in tempest seas. Much more interesting! These coasters are rimless, hence they have no top coat so the colors are deeper and more vibrant.
Coasters come with a cork backing unless the stones were just too pretty on the reverse, in which case they have clear rubber stomps, about 1/8" tall.
Dimensions: 4" outside diameter Side thickness is approximately 1/4 - 1/2" on average.
