K'NEX Roller Coaster 63030 pieces and parts but Not Complete includes Manual for roller coaster Plus Other Parts from other sets includes about 10 Lbs of parts and pieces and yellow container. Overall weight including shipping box is 17 lbs. What you see is what you will get. Lots of knex pieces mostly from roller coaster. Did not count but there are a lot of pieces as you can see from the pictures. There is a chance all pieces are there for the roller coaster but I don’t know and didn’t want to go through the manual to check. So please consider it a fun group of parts to be sure 😊

***Parts manual and Box weight 17 lbs, I had to take apart most of the parts to fit in shipping box.
