This is a used item, purchased new and used by a child. I have confirmed that it is working properly for this listing. I am selling the basic set and the working kit together. I have confirmed that all the block parts are present, but I apologize if I missed anything. I thought two of the parts in photo 9 were missing, but I found them later as shown in photo 10, so there are no missing parts. There are no missing cards, but some have peeled areas and minor scratches from use. The instruction manual has some folds and signs of use. Some pages are torn as shown in photo 11, so please check the photos. I will remove the batteries before shipping.
