It was a family heirloom. Sanyo Toki Ryuhogama Shokamonn Small Bowl Set. This is a rare item, very beautiful and luxuriously made. It's so gorgeous that it would be perfect for special occasions. Some of the bowls have slight discoloration on the back, and while I believe they have been used, they are mostly in beautiful condition with little sign of wear. The size is 13 cm in diameter, making them easy to handle. Please refrain from purchasing if you are looking for a perfect item or are concerned about minor details, as this item has been stored at home. We plan to ship via Eco-Mercari. Thank you for looking.
