I believe this is a cut glass piece from Sasaki Crystal, a round dish featuring a beautiful design. It has been stored in a cupboard for many years. It is a vintage item from the Showa era. Please only purchase if you are not concerned about this. m(_ _)m Highest point: 6cm, Width: 20cm. Suitable for sweets, desserts, or other dishes. Please note that I may use recycled packaging when shipping. Thank you for looking.
