I've used this three times, but I don't plan to use it anymore, so I'm offering it to anyone who needs it. I've stored it at home, but there's some peeling on the back paper. Please check the photos for details. Otherwise, it's in good condition. ● Seat size: approximately 16cm x 25cm. ● Height when in use: approximately 11cm. ● Height when stored: approximately 6.5cm. ● Used a few times. Beautiful condition. ● Please make your judgment based on the images.
