Kiyomizu-yaki Teacups - Set of 5 From my grandmother's ceramic collection, these are new and unused. The bottom of each cup is marked with "Otowa." Size (approx.): Top diameter 6.4 x Bottom diameter 5.5 x Height 8.8 (cm) These teacups are very light and thin, with a refined feel, making them comfortable to use. They are a type of pottery that has been loved for a long time. Thank you. Teacups - 5
