Naturally ingenious, beech wood

Our cubes come from the forest - more precisely: from sustainably managed Swiss beech forests. The wood is robust, durable and comes directly from the region.

Each cube remains untreated, completely natural - so you can still feel the characteristic feel of the wood. Because it not only looks good, but also shows responsibility, it bears the "Swiss wood" label.

Genuine sustainability from nature - a raw material that grows with you, just like the joy of playing.

Playing safely

CUBORO elements are robust, durable and naturally free from harmful substances - so they are safe for skin or mouth contact, even for people with allergies. To ensure that everything runs smoothly during play, each Element is carefully sanded - for clean edges and a safe, pleasant playing experience.

Our marbles also play it safe: they meet the highest safety standards in the industry. Nevertheless: small balls - big effect. Please keep out of reach of children under 3 years of age.
