Cuboro Duo

Made in Bern, Switzerland by Cuboro

A Swiss-made beech wood marble run set for children aged 8+. With 16 cubes and 5 marbles, DUO is designed as an extension to standard sets for parallel building. Crafted from untreated Swiss beech wood, it lets children build two tracks to race marbles against each other or tweak sections until both finish simultaneously – making it ideal for experimenting, comparing routes, and shared play.

About the Maker

Their Story

In the Bernese Oberland, Cuboro has been making its wooden marble run system since 1986. Wooden cubes with grooves and tunnels stack to create tracks where marbles roll through visible paths and hidden passages. What began as a teaching tool for children with special needs has become a multi-generational system of over 100 elements, made entirely in Switzerland and built to be passed down.

Care Instructions

Wipe clean with a soft, damp cloth. Avoid harsh cleaners or soaking. Store in a dry place away from direct sunlight. Wood may show natural variations in color and grain over time – this is the character of living material. Glass marbles: keep out of reach of children under 3 years.
