This item was received about 40 years ago. I don't have specialized knowledge, so I'm not entirely sure, but after researching, it appears to be a tea utensil by Takazo Furuse. It is unused but has been stored at home for a long time. I am selling it because I have no plans to use it. I would appreciate it if those who understand that it is a home-stored item would purchase it. Diameter: Approximately 12.5cm Height: Approximately 8cm Wooden box: Approximately 14.5cm (length and width) Height: Approximately 11cm
