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. This product is recommended by "spielgut" (good toy guide)

Note about Grimm's Wooden Toys: Grimm's are made from natural materials and as such, will have variations in markings. The non-toxic stains show the beautiful characteristics underneath. These variations in wood grain, knots, texture, or stripes are a sign of their high quality natural materials, and are not a defect.
