3 sets all mixed up in the 2 storage boxes. I am not sure if all pieces for each set are accounted for, but I think all 3 can be created since there are extras from the other sets. Also included is the battery operated power tool that helps screw the pieces together (my 8 year old was able to use with ease).

Shipping is free, however due to size and weight of this item, I will ship using the cheapest option at the time of purchase.
