These bowls were stored stacked in my parents' china cabinet. They are a set of 3 large bowls, approximately 25 cm in diameter and 6.5 cm in height. I don't know the frequency of use. There are areas where the brown rim has a patchy color, appearing chipped (photo 6), though it's unclear if this is from the beginning or from use. Also, there is some soiling on the bottom (photos 8 and 9). Please understand that these are used items that have been stored at home for a long time. Thank you.
