This is for a STEM Aero Space The Shuttle Launch Center blocks # 70018 Pcs 566 set. The box has been opened several block packages are still sealed inside. I did not count to see if it’s complete or not. Sold as is! Smoke free home. Please ask if you have any questions. It will be shipped with a tracking number. Please check out my other auctions as I have several listed. I’d be happy to combine shipping on multiple items. Thanks for looking!
