Please note: the Cornerstone set has somewhat sharp corners and edges. It is an excellent set to use in building Grimm's marble runs, and in other kinds of construction, but it is not recommended for children younger than 5 years.
Grimm's 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 Grimm's products must be ordered separately.
Made with European white beech wood. Coloured with water-based, non-toxic stain.
NOTE: If you clean Grimm's wood products, only use a damp cloth. Please do not submerge in water and do not use disinfectant or hot water.
Recommended for ages 5+
Made in Germany.
