Hubelino promotes children's development in a playful way: while children build and construct, they train creativity, motor skills and logical thinking. The 85-piece Hubelino starter kit contains a selection of all the building blocks that are necessary for the creative construction of a dynamic marble run. The combination of the track elements breaks through previous limits in the construction of the ball track and this creates many more possibilities for creative and individual design. 100% Compatible with large building blocks/bricks from other manufacturers.
