A good grip for the elements of this game. The little fingers can manipulate without difficulty. Certainly, younger will not follow the instructions to make themselves car or truck, but their parents can attend and will be very proud. The color code will be useful: blue screws, bolts red, green L, etc.). The boy to whom this game was offered to the appropriate result is to manufacture all kinds of things straight out of his imagination: sword, pistol, scooters, monster He screwed, screwed, screwed again, with the key, with fingers. He loved it. The number of parts is enough and varied enough for a first encounter with this type of games. Rubber, the child can not get hurt. For me it is a great toy to offer without hesitation to small yourselfers.
