This qaba truck engine toy set is a great way to introduce your kids to the basics of equipment maintenance under the hood. It offers hands-on learning, imaginative role-playing and confidence building through a variety of fun activities and many "repairable" parts. Each part can be removed for "repair" and then reinstalled with screw fasteners. You'll enjoy sharing engine knowledge and watching kids do all of these tasks: open the engine cover, replace spark plugs, remove the motor and more.
