Misleading Photo The ball is not really as it is filled with spherical pebble. There even has moçeaux stones that distort the leather in places. So the curve, curvature of the ball is absent and there are bumps The ball 1 kg is 9 cm in diameter ad unlike the 13 cm; and it is for this reason that I had bought. it missed again The seams (points) Have nothing to do with the photo: Spacing points every centimeter (not nice at all like work; I do as well)
