This is a Kyu-su teapot and three teacups from Koransha. They were found while organizing my parents' house. The Kyu-su was used once or twice and then stored in the cupboard. The teacups seem to have been used several times, but there are no chips or cracks. ★Please note that these items have been stored at home and are being inspected by a non-professional, so there may be oversights.
