This beautiful, natural-colored Rainbow Stacking Building Set features 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 wonderful bedroom or nursery decoration. This delightful stacking toy is made from high-quality, responsibly sourced materials that are stained (rather than painted) to create a natural wood effect. Wooden stacking toys help develop children's creativity and dexterity as they feel, play, and create with the wooden pieces.
