marble run extension "Tunnel"

Who doesn't like to remember their childhood marble run? With the innovative "Tunnel" marble run extension from CUBORO, kids can let their imagination run wild. The marbles disappear inside the marble run system, whizz around the curves and reappear somewhere else. Fun is guaranteed and there's definitely no chance of getting bored.

The set is intended as an extension of the standard models, but can also be used on its own.
Also good to know: all CUBOROs can be combined with each other and thus expanded as desired.
