The ball is the seller description, has been fairly fast delivery (barely a week). As. Is a great ball it is not necessary to inflate with helium to fit right, it's been a small effect. Only weaknesses, the next day a small hole appeared on one of the arms (the ball was perhaps a little too bloated) and that lack of explanation for inflation (must insert a straw or a pump rod in a small hole on one of the feet and the explanation is not written anywhere). I recommend all the same.
