Exercise ball has sand in it?

My sister recently just bought my mom a Reebok anti-burst Stayball. Before she even opened it she noticed that there was sand pouring out from the cracks of the box. When the box was opened up there was sand all over the ball. She just recently found out that sand is suppose to be in the ball for the type of ball that it is…i assume. There was just so much sand coming out of the ball, wouldn’t the sand have to be inside the ball, not all over it? Is it possible that the ball is broken or is that much sand suppose to come out?
Thanks for any comments!

probably, i have one and it wasn’t like that at all.
