Blocks & Marbles Set

With this set of 41 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 10 channels, each with an opening, that permit a marble to travel horizontally and drop through to a lower level, and 23 assorted tunnel blocks for supporting the channels without obstructing the path. Each of eight cubes has a wide entry and a built-in turn that allows the track to change direction. Includes 10 marbles.

An engaging activity with great play value, for ages 4 and up. Made in USA.
