Building Set Cornerstone (Grimm's)
A building block really has what it takes - it allows tricky and surprising layering variations and develops spatial thinking. This is how new and various objects in different color patterns are created over and over again. In combination with our classic building materials, the Cornerstones reveal their true greatness. With their aid, the most diverse marble runs arise. Beech wood, non-toxic water based color stain.
We recommend the Large Stepped Pyramid and Geo Blocks, the Giant Building Blocks, and the Wooden Balls and 35 Wooden Marbles for the creation of marble tracks. What can you create?
Please note: Starting in September 2020, the cornerstones will feature new beveled edges to each block.
