Every little child loves dinosaurs, but dinosaurs on wheels make them even more fun. Watch as the little ones crawl around and roll them all over the house. No paints, stains, nails, or screws are used in the construction of this kid-safe toy. All hardwoods pulled from local trees found in Nebraska and surrounding states. While other toymakers use paints and stains we use high-grade, nicely figured woods, (walnut, cherry, Bubinga, padauk, maple) for our toys. Approximate dimensions: l - 6", h - 5", w - 2" Non-toxic food-grade mineral oil safe for babies and toddlers. Please be aware all woods used do vary slightly in grain and color from what is seen in the picture.
