This listing is for a super K'Nex Mighty Makers Home Designer building set - Brianna & Sophia.  Box and pieces appear to be in excellent condition, but I did not count out each piece to make sure that it is all here...most has to be, though, with this big of a pile of pieces.

Our home is smoke free and pet free, but I cannot guarantee that all items have always been in a smoke free and pet free environment.  I am sensitive to smoke smell and will note it when I notice it.  I do try to describe things as well as I can.
