Thames & Kosmos Games Gecko Run: Marble Run Loop Expansion Pack

With the loop, you can bring even more speed, action and experimental fun to your Gecko Run marble run. The additional track elements mean that the marble run reach is expanded, so you can cover even more tiles, doors, windows, shelves and other surfaces.
