Thank you for viewing. This is a set of three Kutani-yaki sake cups from the old days. (Kutani Hachiro, Eiraku, Fuku) The details are unknown, but it seems these were gifts that were never used and have been stored for a long time. Although they are unused, the boxes have some age-related staining. I think each one is unique and lovely, with the distinctive color usage of old Kutani, such as the use of red and gold. They would be beautiful to display, and perhaps it would be nice to change them depending on your mood each day when drinking sake. Diameter: Approximately 5.3-5.6 cm (there are individual differences), Height: Approximately 3.3 cm. Please forgive any errors as this is amateur measurement. Thank you.
