The Gecko Run Starter Set, along with the exciting expansions Trampoline and Looping, as well as two trick elements in one box, transforms the entire apartment into a playground. With the residue-free adhesive nano pads, the tracks can be individually attached to vertical, smooth surfaces and adjusted in seconds. Children will discover for themselves how gravity affects their ball and when it gains the most speed. Whether over obstacles, on doors, glass panes, tiles, or shelves – with the ball track from Kosmos, building can be more flexible than ever before.
