What it does: A graphic instruction manual that illustrates key Cuboro concepts and provides a variety of models to build.

Why buy it: Cuboro is one of our favorites here at Oh! Toys.  Part marble run, part puzzle and part developmental and educational marvel, Cuboro is truly a "heritage toy" -- one which not only can be passed from one generation to the next, but which children will come back to time and again as they grow and become more sophisticated about their creations.
