This item was displayed on a sideboard for about 40 years. It was used once or twice. It has a nostalgic design. The bottom of the teacups is marked with "Kozan." I don't know the details. This item is not subject to price reduction. Thank you for your understanding. Size: Diameter: Approximately 7.5cm Height: Approximately 4.5cm There is no box, so it will be packed with bubble wrap and other cushioning materials for shipping.
