With this set of 45 unfinished hardwood blocks, you can build almost any number of marble runs ranging from simple designs to complex networks of pathways and vertical drops.

Well designed and durable, the set includes channels, each with an opening, that permit a marble to travel horizontally and drop through to a lower level, and assorted tunnel blocks for supporting the channels without obstructing the path. Each of the cube has a wide entry and a built-in turn that allows the track to change direction. Includes 4 marbles.
