The combination options of the Kullerbu play system are as colorful and varied as the play system itself: the Kullerbu tracks can be flexibly combined. This encourages the imagination and creativity of little Kullerbu builders aged between 2 and 8 years, and ensures even more variety when playing. If the track needs to grow upwards or in length then you generally need additional "construction material" in the form of pillars, straight sections, curves and connecting elements. All this is included in the practical Kullerbu expansion sets. This is an expainson set for the Kullberbu system. Allowing to create higher track section. Include 6 columns of varying heights, and 4 connector sleeves. The columns bring height into play and are each provided with height indicators ... both as numbers and as dots. Younger children will usually need some help with the assembly, while older children can experiment by themselves with the various pieces and heights. Combine with #300849 Connectors and Bases and any of our additional track sets to add even more height and fun to your existing Kullerbu set! This expansion set is made in Germany.
