We have received this as a Christmas present to our 2 y/o. She is now 3 and she loves this set, plays everyday. Once you build the house, gives countless hours of joy to the kid. It is nice for story playing. Also, can build different houses to make an Hello Kity town. Completely compatible with Lego Duplo. Stickers come out pretty fast, but once you clean them, indistinguishable from original Duplos.
