I ordered this for my 4+ year old granddaughter and have received two kits so far. This box is amazing! My only issue is that it is far too mature for my just-four-year-old. However, it may be possible to adapt them to a younger child. I haven't cancelled, so I plan to use whatever I can and set aside the rest for a year or two when she is more ready. Makes a wonderful gift!
This is a perfect rainy day "unplugged" activity for my grandchildren. They LOVE to open their surprise box and do the activities together. I rarely hear the usual cousin bickering as they explore and create.
