Diameter: 12.3cm Height: 7.6cm (including foot) The material is unknown as I don't remember. I purchased it for my room a few years ago. This is a versatile bowl, a good size for soups with lots of ingredients, such as donburi or zoni (New Year's soup). There is some wear and tear from use, as well as scratches from storage. I believe it is in a condition that does not hinder daily use, but please examine the condition closely by enlarging the photos. There are small scratches on the sides that are visible upon close inspection, but there are no major chips. I was unable to take good photos due to reflections, so please understand this. Please refrain from purchasing if you are concerned. The listing may be ended suddenly.
