The Grimm's Large Building Rollers Rainbow are wonderfully tactile and versatile construction pieces that add an element of movement to playtime. Whether they are being rolled, combined with other building pieces and figures to create castles, palaces, and entire cities, or used to encourage motor skills development through a stacking game, the possibilities for creative play are endless.
 
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.
