Based on the color, it's likely Hagi-yaki. (All pieces have the characteristic "cut marks" of Hagi-yaki) It's a very ordinary teacup, less than 10 cm tall. It was stored in a warehouse. There is age-related deterioration. Sterilized with boiling water. I estimate it's from the Showa era. Not recommended for those who are sensitive to imperfections. Please purchase only if you understand that it is a used item. No smokers. Not recommended for those who are sensitive to imperfections. Shipping via Yu-packet Plus is planned. #SumireHagiYaki - Bulk purchase welcome! #SumireDishes
