Arita-yaki, Imari-yaki, Nabeshima-yaki... it's a bit complicated, please check the photos for confirmation. I found this while cleaning the house, in the top cabinet. It's unused. I've never seen it before either. It's boxed, but the box has scratches. There's one spot on the foot that looks like it was made that way. The box is secured with a clasp. Dimensions: Diameter 20cm, height 5.1cm, foot 17cm. These are my measurements, so there may be some error. Thank you.
