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.  

The original Cuboro starter set!  54 equal sized cubes with 12 different functions.  The ideal place to start with this great toy, Cuboro Standard has plenty of blocks to let your imagination run wild.  Comes with 3 Cuboro marbles.  Visit Cuboro's home site in Switzerland for additional images and information.  Ages 3 and up.  CAUTION:  Marbles can represent a choking hazard to very young children.
