The master construction kit exceeds all construction fun with the marble track. Due to the enormous number of components there are countless construction possibilities. The large speed circle, the track with sound effects, the waving flag and the marbling canon also guarantee exciting effects in the marble tracks. The best thing is the sophisticated universal pipe clamp, which allows the marble track to be built to unprecedented heights. Attach it to the edge of a table or rack, increasing the slope and the marbles at top speed.
