The click-together race track system ensures easy, frustration-free setup that encourages independent building making great educational toys for 3+ year old and 4 year old toys. Whether your child is racing balls through loops or lining up dominoes for a satisfying topple, this set offers open-ended, screen-free fun. Crafted in Germany from toddler-safe materials and compatible with all other HABA Kullerbü sets, this expandable playset is a perfect gift for curious minds. Great for birthdays, classrooms, or everyday play, it's an exciting entry into the world of toy building sets, STEM toys, marble runs, and building toys for kids ages 2-5+.
