This is a free-size, 100% cotton "sarashi obi" (belly band). I received it during a prayer for a safe delivery, but I didn't use it, so I'm selling it. I haven't tried it on or used it, but I did take it out of the box to check the contents. It's not brand new, so please refrain from purchasing if you are overly concerned about this. Retail price: 2750 yen You can check how to wrap it in a video.
