I received this from my grandfather, but I have no opportunity to use it, so I am putting it up for sale. I was told it is an obi (kimono sash), but I don't have detailed knowledge, so I will sell it as is. Please check the photos for any scratches or stains. There are some minor frays. I don't have detailed knowledge, so I will answer questions as best as I can, but I may not be able to answer specialized questions. Thank you for your understanding.
