All Levels Love It: We include a full-color manual with 42 patterns and challenges from easy to difficult. The little ones love the tools drilling the screws into the base. The bigger kids love the complexity of the building. Our educational building blocks grow with your child, too. Education Toy: Perfect for giving your little engineer a leap in their skills! Each Kids Drill and Screw Set maxes out their spatial awareness, logical problem solving, visualizing and planning, fine motor skills, and many other essential cognitive skills through our puzzle building toy!
