I purchased this last year for use in Pilates stretching and have stored it carefully in a dark place. I think both children and adults can use it. The outer bag was in this condition from when it arrived. The ball is clean. It will be shipped deflated. Please inflate it with a ball pump before use. Please be careful not to overinflate, as this may cause deformation. Available for immediate purchase. Thank you.
