"My 6 year old is just getting into Lego building and she simply loves Frozen merchandise. So this was perfect set. She graduated from the 30-40 piece small cars to this 500+ piece so I was wondering if she would tire out and not want to build it completely. However the pieces were well organised and divided into 6 steps so my daughter took her own time and built it in steps. The outcome was beautiful. There are so many details and moving pieces that building it is only half the fun. The castle has a lot of moving pieces and other details to allow for endless hours of role play fun. A must have product fir Frozen and Lego fans."
