It was a very good purchase, me and my colleagues at work like it so much, it's fun and really helps to relief our stress. Yeah it's not like a real box bag, there is just a ball inside that's pumped up with air but it's still great. Gave 4 stairs because it's a bit unstable, it comes up from the table after a while so we have to be careful with hitting it. There was a ball pump as well in the package so thank you!
