This is a used fukuro obi (formal obi). It's very beautiful, and I believe it incorporates seashells. However, there are small white spots on the black areas, which are not the main design. They might come off with cleaning. Also, it has been stored in a tansu (Japanese chest of drawers) for a long time, so it has a tansu smell. I will only be listing this while I'm visiting my parents' home, so I may remove the listing in a few days. It will be shipped via Takkyubin (courier service).
