The new Coaster Dynamix Marble Racing Roller Coaster is an exciting 3D wooden puzzle kit. Be enthralled as the marbles race around a realistic roller coaster track and spin the checkered flag. Assembly is straight forward with no glue required. All parts press fit together. The model comes pre-painted in vibrant colors. At approximately 2 feet in length, this kit is large enough to enjoy, yet at under 6” wide, it’s narrow enough to fit on a shelf for display.
