This is a tumbler purchased at a-nation in Nagaoka City, Niigata Prefecture in 2006, when Tohoshinki started their activities in Japan. It can be used for tea, coffee, etc. It is about 12cm tall and 8cm in diameter. The drinking spout can be opened as shown in photo 5. It has been carefully stored in a dark place, but a considerable number of years have passed. Please understand that this is a personal item, and I appreciate your understanding.
