Flexible, vertical, and completely free: With the combination of the starter set and the ingenious expansions Trampoline and Looping, along with two extra tricks, spectacular marble runs can be built. Bendable tracks, rapid curves, and clever levers: Each component is individually attached to vertical, smooth surfaces using residue-free nano adhesive pads, allowing for quick adjustments and fine-tuning in seconds. Whether over obstacles, on doors, glass panes, tiles, or shelves – the Big Box of the KOSMOS Marble Run Gecko Run tests what is possible! Completely free, without restrictive support structures and without cluttering the floor – it's a huge fun, even for on-the-go play. Children aged eight and up decide how challenging their track will be and how they experiment with free fall and gravity. 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 made in Germany.

The Gecko Run Starter Set, with the fast-paced expansions Trampoline and Looping, as well as two trick elements in one box, transforms the entire home into a playground! With the residue-free nano adhesive pads, the tracks are individually attached to vertical, smooth surfaces and can be quickly adjusted and fine-tuned in seconds. Children will discover for themselves the effect of gravity on their marble and when it gains 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 produced in Germany. For children aged eight and up.
