There is a "Narumi China" imprint on the bottom. This was used by my parents at their home long ago. As it is an old item, it is not in perfect condition, but I believe it can be used casually. It is made of a fine-grained material, is light, and has a small size that fits comfortably in the hand. It may be possible to combine shipping with other items I am listing, so please take a look.
