This HO Scale Roller Coaster kit has never been put together. Photos above show all parts are still intact on the sprues. Everything is included in the box and ready to build. Very detailed kit and appears to be a good size once constructed. Must sell Only in the U.S.A. Size of the box is 22 inches wide, 15 inches tall, and 4 inches deep. Weighs 8 pounds. This is the dimensions of the base plate for the coaster so this is a good size model.
