The box with the basic building blocks Lego / Duplo has proven good quality Lego. The only thing we can complain about, is that they - certainly intended by the Group - no stones included with inclined surfaces or stones for a roof, which is why you can not build a house, or not a big gate, or the like. For this you have to buy another box. And no base, but then you have to separate the "Duplo big building board" (the green area), which is why the things are a little uncertain.
