Cuballs (20 piece set):
The Cuballs are available individually as separate add-ons. Until now, you had to purchase Dyna Magz to use the Cuballs, but now you can add them separately to your sets. Cuballs enable you to build high rises and cubic structures. Cuballs is not compatible with the Super Magz series or the Magz-X series

Details:
These 20 Cuballs come in a clam-shell packaging, like Gyro Magz. This set requires one of the other five sets (not compatible with Super Magz 52 and 130). It cannot be used as a construction toy by itself. See Dyna Magz for further information regarding the Cuball.
