Set of 3 Koishikawa-yaki teacups, ceramic, white, red, and black. I received these as a prize and have stored them in a dark place without using them. They appear to be Chikuzen Koishiwara-yaki by Tomitaka Ota. I would like to give them to someone who needs them since I don't use them. Please comment if you have any questions! - Brand: Tenmoku-yaki - Material: Ceramic - Colors: White, Red, Black - Quantity: Set of 3 - Accessories: Wooden box Thank you for looking.
