Kasash, popular at stores like Base, etc. All accessories are included. The retail price was about 4000 yen. This product allows you to attach umbrellas, hand fans, etc., to backpacks and other items, keeping your hands free. I used it when going out with a baby carrier, but I only used it a few times and for a short time on rainy days, so it's in good condition. It was safe because both hands were free. I plan to ship it with the box folded. Quoted from the HP: 1. You can fold your umbrella neatly without getting your hands wet, and the water droplets are collected by the Ishiuchi holder so they don't spill below (for vinyl umbrellas). 2. You can attach charms and straps to create originality. 3. It is possible to secure umbrella vinyl bags. 4. You can attach it to a backpack or bag and move around or shop hands-free. 5. If you attach it to a school bag, you can move safely without being distracted, and your hands are free.
