Diameter at the mouth: 5 cm, diameter at the base: 7 cm, height: 10 cm. My family bought this at a pottery fair somewhere. It's unclear whether it's Bizen ware or Kanzan-yaki. There's a crack-like fissure on the bottom, but it doesn't go all the way through. I think it's a surface crack from the manufacturing process. It weighs 350g and feels substantial. It has hardly been used at all.
