What's included: The Flex-Corner Expansion Pack comes with over a dozen parts to complement the Gecko Run Starter Set, including 90-degree outlets and track bridges so that you can quickly change the direction of your marble run, bend around corners of any angle, and tackle obstacles with ease! Also comes with two additional tracks, marbles, and nano-adhesive pads.

Innovative: Design your own vertical marble runs with this specially designed system of flexible tracks that does not require any support structures, allowing you to build higher with fewer pieces.

Intuitive & Mess-free: Tracks attach to smooth surfaces with the help of clever nano-adhesive pads that create a strong but temporary bond; the pads are not glue-based and can be quickly and easily repositioned without leaving behind damage or sticky residue.

Tracks are made from renewable raw materials.
