I was excited to recieve my new exercise ball. When I opened it and blew it up the smell of moth balls was so strong it was nauseating ! It smelled up my whole house. So outside it went hoping that it would go away. One month later it had toned down some so I brought it back inside. It had only been inside for 30 minutes and the house stunk again. I would not recomend this ball unless you like the smell of moth balls ! I would send it back , but I didn't keep the box. I guess I am out the money !
