This is a masu (wooden sake cup) given to me when I entered the "Naoirai Mode" of the "Nurunuru null2" event on the closing night of the Osaka Kansai Expo on October 13th. It contained sake, which we used for a toast, and I washed it after bringing it home. *Please check the condition of the product in the images. If you have any questions, please ask before purchasing.
