The pump is perfect for inflating and deflating the StretchBall, especially since you'll want to take your ball with you everywhere. The needle unscrews for quick ball deflation, and then you hide the needle inside the pump for safer travel.
***When you receive your pump, be sure to take a look at the top of it, twist off the black cap and find your needle safely tucked away inside and upside down. It has a very special holding place. ***** many people write in they can't find their needle. Its there for you. Ready when you are. Roll your way to feeling A MAZING.
