  2. Customer

    We had purchased the smaller set as a Christmas gift and both kids loved them so much we had to buy this larger set. They (5 & 6.5) still play with them every day.

  4. LZG

    Purchased asa gift for my nephew’s. I played with them a bit to test them out and they were fun! Instructions for specific things to build need an adult to help them follow them but I feel like they will have fun being creative and will still have lot of fun with self play! Love that it comes with its own carrying box

    I bought this for my grandchildren when they visit my house. I love it! Lots of pieces. It really leads to creative fun play rather than screen time at my house. Thank you for a great product
