Create your ultimate vehicle fleet with this cool magnetic toy set! Each one rolls on real rubber tires and has a movable feature. Our magnetic locking system makes assembly a snap and allows you to put your vehicles together and take them apart again and again. Large pieces are safe for little ones. Combine them like a 3D puzzle to make your favorite trucks, or mix and match the six chunky truck body parts to create new vehicles! All build-a-truck sets are compatible!
