My son received this gift for Christmas. He adores !!! He piles it symmetrizes, he makes his own history with animals and especially they are never the same. Whenever he resort to his box Duplo, he invents something else. Legos are of very good quality, easy to handle due to their size and attractive by their color. The animals easily fit together on the bricks and the unbreakable air. I recommend this purchase, your kids will love !!!
