This is a drawstring bag that came with Yanagiya Honpo. It contained bonito flakes and other items inside. I only took out the contents and have not used it. Please refrain from purchasing if you are concerned about it being stored by an amateur. It goes well with yukata, and I think it's also good for storing underwear or small items when traveling. I believe it's large enough to hold a bifold wallet, a hand towel, and a mobile phone. Yukata bag Accessory case Drawstring bag Yukata Kinchaku
