AOAVE 2 Pack Pilates Ball, Yoga Ball, Barre Ball, Mini Exercise Ball, 9 Inch Small Bender Ball, Pilates, Yoga, Core Training and Physical Therapy, Improves Balance

Have to be quick to plug after inflating.

Grateful it came in a pack of 2, because I misplaced the 2nd stopper. Great ball. Needed for yoga.

I bought this for my daughter to use at a Ballet conditioning class. She has to use the instructor's ball because these balls do not hold their inflation. Once you blow them up they start to lose air immediately. The stopper is difficult to replace therefore loses air.

I was disappointed with this item. First, the pictures showed the balls inflated. Second, there weren’t any instructions or information on how to inflate them. If you’re going to sell these items as you currently do, don’t assume that everyone knows how to inflate a ball.
