This is a set of "yutan" (cover) and "koto-bukuro" (koto bag) for the koto. The set features a cute "sakura (cherry blossom) pattern." We are offering it at a discounted set price. I, the koto player, handmade these items. This is a yutan for a 13-string koto, remade from unused or used vintage silk obi. The ribbon ties are made of [silk or polyester, etc.]. Some may have seams in the middle, but they are hidden inside the yutan and do not pose a problem. These are primarily made for kotos around 185cm in length. The yutan ties are designed to be removable, allowing for washing or replacement if they get dirty. [Please note that these are handmade items, so there may be some imperfections such as slight distortions or misalignments. The color may appear slightly different in person than in the photos.] This is for those who understand and appreciate handmade items. Thank you. The items will be folded, placed in a plastic bag for waterproofing, and shipped in a Nekopos box, a recycled paper bag, or a宅配ビニール袋 (delivery vinyl bag), depending on the thickness of the yutan. *Please take a look at my other listings as well. ※The koto itself is not included.
