I'm not sure what type of pottery it is, but it's a small, easy-to-use bowl with colors that aren't too strong, in the brown and blue families, making it compatible with various dishes. It has been stored at home for a long time, but it's in beautiful condition with no signs of use. The brown color on the underside of the bowl is not a stain, but the color of the glaze. This is the final price, so thank you for your understanding.
