This item has been stored at home. Used a few times, and washed with oxygen bleach. 22.5 cm (height) x 16.1 cm (width) x 3.3 cm (depth) One plate has discoloration. (I remember putting it directly on a flame once.) I believe it was made in Japan, and it's well-made. Can be stacked. Will be shipped using recycled packaging materials. I do not use synthetic detergents due to chemical sensitivities.
