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 the Giant Building Blocks, the Wooden Marblesthe 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 three examples (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.

We can't wait to see all the inventors and architects out there!

Beautiful and versatile

The cornerstones were an addition to our collection for making marble runs. They have so many more uses than that, though! My kids put four together to make 'tents', stack them as high as they can for pretty towers, use their brains to figure out how to put them together in the box properly, use them in buildings they make with their toys, use them as decorations in small worlds etc. They're light and have an amazing feel, inviting children to come and play with them!

Essential for ball runs

Must have to accompany a Grimms large stepped pyramid for ball runs!! Plenty of hours of fun using these cornerstones. My kids have used them for ball and marble runs a plenty!!!

So many uses

These cornerstone blocks help take building and ball runs tot he next level. The colours are complementary to both the pastel and bright Grimm's colours. When I first received them I thought they seemed small. But in the right place the size makes sense. The box to contain them all is also really useful. Everything you'd expect :)
