I vaguely remember using this in a Kawai gymnastics class when I was in the middle grades of elementary school, about 7.8 years ago, and it's been stored at home ever since. The air is out, and it's dented as shown in the photos. I haven't tried inflating it with an air pump (as I don't have a ball pump). It might inflate after purchase, or it might not. There's a name written on the sticky note. It doesn't bounce at the moment, but I thought someone might need it, so I'm listing it. My child used it about 2 or 3 times. I'll see how it goes, and if there's no interest, I might take it down.
