On the strength of legos, there is nothing to add because it is known and recognized that these pieces of bricks ... go from generation to generation. There are 3 explanatory booklets, fine detail and color to achieve the house and characters like the picture of the box. The details are impressive: flowers, cutlery, bathroom, brushes, etc .... The child can also invent his own construction. My grandchildren (boys) have created the kinds of "bastions" for "history" with other legendary characters. This is a very high quality box, diversity and colorful. The rooms are divided into: 7 numbered bags, a bag plates and 2 plates in bulk. Tip: when you open the bag, put the items in small boxes and do not mix the elements. It is easier to recognize the legos to build after the booklet. Advisor purchase.
