This item was at my parents' house. I believe it is Kawatsura lacquerware. It seems this was kept in storage. It's unclear if it's unused, but I don't see any noticeable scratches or stains. However, it has been stored for a long time, so please consider this before purchasing. Diameter of the top: 13.5cm Height: 9.5cm I think it's a tea ceremony utensil, but you can also use it as a bowl by removing the lid ^_^ Please forgive any oversights.
