I was a bit surprised to see this happen deflated balloon in a small carton, I was expecting a slightly larger package. It was not a worry, a bit of a compressor and this is inflated to 0.7 bar. For one who is not equipped with a compressor, a small bicycle pump with the needle tip and voila; Although it is not known if it is inflated to 0.7 bar but after that is a matter of judgment to touch and rebound. And now there is more to ....! The ball is nice and the plastic a little hard the first kicking ball but like everything, it takes a little time for it to "do". To see how it will behave over time, especially at the seams as it is often here that the first signs of fatigue appear. Anyway, this is a good quality / price ratio.
