The Speed Wheels are Walgreens 1/64 scale maisto cars. ALthough they are the exact same castings as the Fresh Metal cars and the Adventure Wheels cars they make it easier to find the cars you like by just having to go to Walgreens, rather than Walmart of any where else that sells them. The castings are the exact same models as the Fresh Metal just on different cardings. They also have speed wheels 5-packs. Unlike the other cards the speed wheels have different series of cars. The new series comes out each year.
