The Ravensburger Gravitrax Tube Expansion Set is designed for fans of creative marble runs aged 8 and over. The rotating tube allows marbles to be held on the track and then released, creating new possibilities for planning the movement of the marbles and building sophisticated tracks.
The set is an accessory for the Gravitrax starter set, which is required for play. It includes an illustrated instruction manual and parts for expanding the track. Please note: due to a manufacturing error, the product has packaging from a different model; the contents of the set correspond to this product.
