I ordered the ball to Nicholas for the children in my class, it is accordingly for two months in continuous use in all weathers on the asphalt of our schoolyard. The envelope has so far held up well, even after a week on the canopy of the school. The children are very satisfied by the Schaumstoffamterial the injury when shooting in the face or to the body are low. I still have a few spots with football Edding painted on, now it's perfect. A week ago, we got even given the smaller version that is too small, but quality is also good.
