There exist in fact two kinds of semi-trailer of Cars, which is confusing: it might contain 18 cars but actually measuring between 2 and 3 cm !!!! Car size eggs surprises !!!! I was also very disappointed by this truck and not only by its size but by its weight as light as a small car Cars and all molded plastic of very poor quality. It is obvious that the price is not in line with its size and quality finishes, far from it .... For a gift, it is very limited and even ridiculous. I can only advise against it .....
