This beautiful natural colored Rainbow Stack building set has soft, warm tones and comes with 11 wooden arches. Imagination is the only limit to playtime possibilities with this wooden stacking toy.Will your little one build bridges? A tunnel? Half a pizza? We love it because when playtime is over it makes a wonderful bedroom or nursery decoration. This delightful stacking toy is made from high-quality, responsible materials that are stained (rather than painted) to leave a natural wood effect. Wooden stacking toys help develop children's creativity and dexterity as they feel, play and create with the wooden pieces.
