I was a little dubious on leaving the ball from the box. I thought it was going to get tired pretty quickly my daughter or not interest him at all. On the contrary !! She loves that ball! The ball is big enough, it is the size of the head of a child. It is very light. Both rigid (so easy to catch) and soft (so does not hurt if launched). There are a dozen small plastic balls of different colors inside. My daughter (who is 16 months) takes a great pleasure to shake the ball to see them move. The ball bounces very well on the ground, even when it is dropped from a small height. It seems solid, the cat played with and, well, no harm done yet! The price seems reasonable. I would not have considered putting more than 10 euros a ball anyway. I think it's a toy that may appeal to children 1 to 5 years.
