Flexible, vertical, and completely free: With the combination of the starter set and the brilliant expansions Trampoline and Looping, along with two extra tricks, spectacular marble runs can be built. Bendable tracks, fast curves, and clever levers: Each component is individually attached to vertical, smooth surfaces using residue-free nano adhesive pads and can be set up, adjusted, and fine-tuned in seconds. Whether over obstacles, on doors, glass panes, tiles, or shelves – with the Big Box of the KOSMOS Marble Run Gecko Run, everything that is possible is tested! Completely free, without restrictive support structures and without cluttering the floor – it's enormous fun, even on the go. Children aged eight and up decide how challenging their track will be and how experimentally they want to handle free fall and gravity. Here, the track grows with their experience. Durable materials, a clever concept without support structures, and tracks made from renewable resources – this marble run is resource-efficient and manufactured in Germany.

The Gecko Run Starter Set with the fast expansions Trampoline and Looping, along with two trick elements in one box, transforms the entire apartment into a playground! With the residue-free nano adhesive pads, the tracks are individually attached to vertical, smooth surfaces and can be set up and fine-tuned in seconds. Children will discover for themselves the effect of gravity on their marble and when it gathers the most speed. Whether over obstacles, on doors, glass panes, tiles, or shelves – the KOSMOS marble run can be built as flexibly as never before! Sustainable: All tracks are made from renewable resources, and the marble run is manufactured in Germany. For children aged eight and up.
