Grimm’s Cornerstones from Oskar’s Wooden Ark opens a whole new range of possibilities. This set allows tricky and surprising layering variations and develops spatial thinking. This is how new and various objects in different colour patterns are created over and over again!

In combination with Grimm’s classic building materials like theGiant Building Blocks, theWooden Marbles,the small and large stepped pyramids,Building Boards, the Cornerstones reveal their true greatness. With their aid, the most diverse marble runs can arise.

We have added threeexamples (see photos)on how to build your own marble run made of Grimm’s Wooden Toys. It can take some experimenting until the step height matches the ball size and the optimal distance between the cornerstones is found. Tricky building and construction for adults and playing fun even for the little ones. If everyone works together, great things can happen.
