Item Type... Shallow Bowl/Sashimi Plate It has been stored outside of its box, so I am unsure of the type of pottery. I believe it is a piece with a design and color that suggests the possibility of earthenware. It has a bit of weight. It's best not to drag it on the table (Photo 4). Approximately 16 x 14 cm, Depth approximately 3.5 cm This is a piece that you can enjoy using with various dishes. Thank you for your consideration.
