Cuboro Book #2 features the plans for 12 master tracks from championship winner Claus Gittner. Gittner reinvents the cuboro system with his surprising combinations of marble tracks. The spectacular courses are outlined in the book for everyone to copy. The tracks in the book are arranged from the 54 cubes of the basic box cuboro standard.

Cuboro is a unique, Swiss-made wooden marble run that is the best-in-class for marble runs.  High quality, and endless in its combinations, inventor Matthias Etter's Cuboro and Cugolino marble runs truly are "marble runs for a lifetime."What it does: An ingenious building block and marble run toy from Switzerland, Cuboro allows endless combinations and designs.
