Assembling the world map was very easy and fun. The pieces fit together perfectly and, little by little, the picture is formed in an exciting way. Everything is completed by various signs and symbols that enrich the picture. The only flaw, in my opinion, is the fact that the flags are very difficult to insert in the continents where the states are very concentrated in a small space, especially in Europe. However I strongly recommend the purchase, it is a truly excellent product.
