This ball is good but pity that it comes deflated, you have to buy the small pump that recommended with amazon (low price and convenient, serve me in the future without bp). Purchased in size 6, but a little big (for a better c size is 4 or 5 children) but before I receive not realize the actual size (lack of indication on that side, it should indicate the diameter with Height). Color is good, it s good air quality to see in time. Purchased for birthday a little boy of 6 years.
