In the Kullerbü play world there are no limits - neither for speed nor for imagination, creativity and flexibility. The ball and play tracks can be recombined over and over again, and expanded. As well as this, Kullerbü is the perfect combination of wood and plastic, deliberately working with the advantages of each material. We think that wood is one of the most beautiful and natural raw materials around. That's why wooden toys have been a firm competent of the HABA range for around 80 years.
