Set of four ceramic coasters made from speckled clay and glazed in a beautiful blue glaze that breaks brown over the edges. The coasters have cork adhered to the bottom to prevent scratching your table's surface. The ceramic holder has a ribbed texture and is glazed the same beautiful blue as the coasters and keeps all four coasters neatly nestled until use. Submersion is not recommended with the cork bottom; simply clean the top surface with a damp cloth. The coaster size is 3.25" in diameter and the holder size is approximately 4.5" wide x 2" high.
