Grimm's Rainbow Building Boards are a beautifully handcrafted set of wooden toys designed to encourage open-ended play. These versatile boards offer endless possibilities for imaginative play, allowing children to stack them to create steps, bridges, lay flat for roads and walk ways, and so much more. They are the perfect compliment to the 12 piece large rainbow, tunnels, and semi circles, as well as numerous other building sets, offering endless balancing and construction possibilities. Made from sustainably sourced wood and finished with non-toxic, water based colour stains, these boards are not only fun to play with but safe for little ones to enjoy.    
 
The outstanding and typical feature of all Grimms toys is the rough yet velvety surface, which is the result of using colour glazes and plant oils that penetrate the wood fibres and leave a lively surface. Especially with building elements, this contributes to greater play value, since the individual wooden pieces do not slip off so easily. All the colour glazes and oils used are harmless, enhancing the natural beauty of the wood, allowing the various markings and grains to show through making each piece unique. 
 
Guided by Waldorf education and other alternative pedagogical approaches, such as Montessori, Grimms design their toys to keep the playing possibilities as open as possible, so that creativity is not restricted, and can develop in new directions. The possible combinations of the individual items are limitless and open up a broad field of infinite playing possibilities. As children's development progresses, they find new ways to play and interact with Grimms wooden toys, making them a perfect companion throughout their childhood.
