Cuboro is a Swiss-made assembly slope/marble rolling machine with endless play possibilities. This is cuboro supplementary parts set. Adding it to the basic set will further expand the world of cuboro. cuboro (Cuboro/Kubolo) Duo is a set that includes parts that can run in two rows. It's a lot of fun to roll two marbles together, have them compete, and just watch. By incorporating parts that change the trajectory, you can change the conventional course to a two-row course, or create a course that doubles the length of the trajectory of one marble. *Since marbles are used, there is a risk of accidental swallowing, so please be careful not to let children under 3 years old play alone.
