This is an Anpanman stretch ball. I bought it at the Anpanman Museum in Yokohama. It seems to be the same type used in the ball corner of the Anpanman Museum. It has only been used indoors, and the frequency of use has been low, so there are no noticeable scratches or stains, but I think there may be small scratches and stains due to use. It's the type of ball that you inflate with air, so the air will gradually leak out while playing. However, it will revive when you inflate it, so please add air occasionally. I have been storing it folded for several months, and I lightly inflated it for this photo shoot, so there are some fold wrinkles, but the wrinkles will disappear if you leave it inflated. The diameter when inflated is about 40-45cm. We didn't recognize it as a balance ball in our house, so we didn't play on it, and we occasionally rolled it around and played catch. There is no box from when it was purchased. I will deflate it and fold it for shipping. If you understand that this is a used item, thank you.
