Warning, this ball has after unpacking a quite strong chemical smell, like him have many other good as new gummy products. However, they are in this ball really strong, and it is the first article of lies with me for such a problem in the basement. Also, I had tried to wash him, so that subsides, but it was not even a reduction audible. After touching smell also my hands quite unpleasant. I can not imagine that this will still improve and I'll send it back to me probably.
