I am selling this item because I no longer need it. It cost approximately 400,000 yen when I purchased it. I have never used it. I have stored it in its original box, so the obi is in the same condition as new. I am a novice when it comes to kimonos, so I cannot answer specialized questions. I am also listing this item on other sites, so please be aware that I may cancel the sale if it sells out elsewhere.
