I'm not sure what it's for, but I think it's something used for kimonos, as it was at my grandmother's house. If you know what it's for, please feel free to use it. I've looked into it, and it seems to be a very expensive item. I think it's quite a find! Please make good use of it☆ Thank you. As you can see in the sixth photo, there are two stains on the front, but they are not visible on the back. It is new and unused, so I will not open the seal to check it, so please understand. m(_ _)m BDO Golden Goose Feather Double Finest quality Hiyoku silk ● This product has been made with the traditional techniques and carefully selected high-quality raw silk for the best Hiyoku.
