These shell coasters are approximately size 10cm x 10cm and made from clear glass with a kiln carved shell motif on the underside. Choose from one of four designs including a Starfish, Periwinkle, Scallop or Spirula shell. These look lovely on their own or as part of a set. The composition of each coaster will vary slightly due to the handmade nature of the work, each is made individually and is therefore unique.
