Cuboro Tunnel Wooden Marble Run Set

Tunnels are what makes the Cuboro wooden marble run system so engaging and thought provoking. This Cuboro Tunnel set expands the tunnel aspect with 13 additional tunnel pieces, 2 building blocks, a marble catcher and 5 glass marbles.

Tunnels within the marble run blocks take various forms, straight lines, twists, turns and level changes. Each wooden piece also has a visible marble run on top allowing for all kinds of building possibilities. Cuboro marble runs have been precision engineered to ensure smooth and confidence inspiring builds. This set can be used as a stand alone marble run but is best used as an expansion pack for the Cuboro standard and Junior sets.

With each Cuboro piece offering various build possibilities these wooden marble run systems really test your skill and ingenuity. Both young and older minds will find building successful marble run a challenge, but once built you’ll feel an immense sense of satisfaction and fun as you watch the marbles make their journey.
