This item likely originates from Arita, Saga Prefecture, as it was found in a warehouse there, and is therefore probably Arita-yaki porcelain. Although unused, there are some scratches on the bottom from long-term storage. Size: Approximately 7.8cm in diameter x 7.3cm in height. Please consider purchasing if you understand that this is an old item and has been stored for a long time. #AritaYaki #Yunomi (teacup) #Pottery
