The new building set cornerstones open a whole new range of possibilities. They are pretty edgy and are coming in 18 pieces and a wooden frame. 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 Grimm's classic building materials like the Giant Building Blocks, the Wooden Marbles, the small and large stepped pyramid, Building Boards (new item 2018) or the Cornerstones reveal their true greatness. With their aid, the most diverse marble runs can arise.
Made from precious beech wood and finished with a non-toxic water based color stain. 18 pieces in a wooden frame, 15 x 15 x 5 cm.
