Brand: CHACOTT
Material: rubber

CHACOTT ball pump for rhythmic gymnastics is made in such a way that provides the optimum amount of air and inflates the ball in small portions.
When inserting the needle into the ball, make sure that it gets into the ball at right angle. Other way you may damage the nipple.
Inflate the ball while touching it by hand. It should be a little bit soft, so you would be able to take it from the top. Do not inflate the ball too much, it can deform it.
