This beautiful natural colored Rainbow Stack building set has soft, warm tones and comes with 11 wooden arches. Imagination is the only limit to the playtime possibilities with this wooden stacking toy.Will your little one build a bridge? A tunnel? Half a pizza? We love it because when playtime is over, it makes a beautiful bedroom or nursery decoration. This delightful stacking toy is made from high-quality, responsible materials that are stained (instead of painted) and 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.
