Diameter 8.5cm, Spout Diameter 10cm, Height 4.5cm This item was given to me by a Japanese tea ceremony instructor and has been stored at home unused for many years. The slightly blackish rim, I'm not sure if it's from the firing process or discoloration from long-term storage. It's not very noticeable (see photo 4). Thank you for your understanding. Please consider purchasing if you are interested.
