Thank you for viewing. Diameter: Approximately 20.5cm My grandmother was a teacher of the Omote-Senke school of tea ceremony and is selling items she no longer needs. She said that everything was expensive when she bought it. I don't have any knowledge of the tea ceremony or the items, so I don't know what they are or who the artist is. I hope you can judge from the photos. As these are old items, there may be signs of aging, stains, and discoloration. Many items could probably be cleaned by wiping or washing, but I am selling them as is because there are too many. *Please refrain from purchasing if you are nervous about used items or are looking for something perfect. Also, as these items are being sold at a low price, returns and exchanges are not accepted. Please consider before purchasing. Management No. 107
