I received this as a commemorative gift for the opening of the family restaurant "Jonathan's." It's a collaboration with Soga Glass "Garden Terrace." This plate is not for sale. Size: Approximately 18cm in diameter x 2cm in height It's from several decades ago. I haven't used it and have kept it stored in a cupboard. There are scratches, but I can't tell if they are from the manufacturing process or from storage. Please understand. #Jonathan's SOGA GLASS GARDEN TERRACE
