Grimms building set cornerstone includes 18 pieces in wooden frame. The frame measures 15 x 15 x15 cm. 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 colour patterns are created over and over again. Wonderful for both decor and discovery play. Can be combined with our large stepped pyramid and geo blocks to create unique marble runs. These additional Grimms products must be ordered separately.

Made with European white beech wood. Coloured with water-based, non-toxic stain.

DAMAGES & CARE OF WOOD: If you clean Grimms wood products only use a damp cloth. Do NOT submerge in water. Do NOT use hot water or disinfectant. Grimms stands for quality and long life. When making our toys, we carefully select the wood without defects. At each step, the quality of the wood is checked. But wood lives and responds to air changes. Wood is a natural product and not indestructible. Children should be advised and prompted to use caution with their special toys. If something breaks, repair the damage with wood glue.
