Used Lego Architecture Studio set that includes idea book and three cardboard trays. Brand new this set includes 1210 pieces. I estimate (I counted pieces that were lose and not sealed in bags), this set I am selling actually includes 2,000+ architecture studio pieces. Of the original set all pieces are represented but in total there are about 1067 pieces. For example, there are some pieces that should total 10 in the set, but there are only 8. The additional pieces included include duplicates of other pieces included in the set including 7 bags of unopened pieces that I estimate contain at least 100 pieces each. ( I had an additional Architectural set and the sets became combined at some point). Slight shelf ware on box and slight tear on one corner. See picture for details.
