An Acorn favorite, this fantastic set is intended to be used in conjunction with other 
Cuboro sets to accelerate the marbles to cover longer distances. Consisting of 16 track building elements with interior tunnels and symmetrically defined functions on the surface, the rails and cubes can be combined to create a myriad of track systems, ranging from simple to complex. A wonderful way to challenge children and engage them in different mathematical concepts in a fun, interactive way.
