Recommended for ages 3 and up, this building set offers endless creative possibilities with its 100 blocks ranging in lengths from 4 to 20 cm. Children can build walls, towers, houses with furniture, castles, and much more. These blocks can also be used to create unique marble runs, for example with Building Set Cornerstone (Art. No 10184). Additionally, this set serves as ideal room decor, inviting everyone to play, and is a wonderful complement to all of our building sets. Through building and playing with these blocks, children develop fine motor skills and spatial thinking skills. The set includes 100 building blocks in a wooden frame, crafted from lime wood with non-toxic water-based colour stain or non-toxic plant-based oil finish.
