A truly mesmerizing marble-track experience! Each set is made up of hollow stacking cubes and a variety of perfectly flat tracks. The paths cut out of each track widen almost imperceptibly from one end to the other, creating an invisible slope that propels the marbles forward. Watching them go is like magic in slow-mo!
This set includes enough pieces and instructions to make many planned constructions, but it's also enough for free-form building. We suggest this is suitable for children of 6 yrs +.
Builder set includes 1 catcher, 1 topper, 55 risers, 5 stainless steel marbles, 10 unique tracks, base grid.
Safety Age : 3 yrs +
