These are the classic smoothie hubcaps. Hubcap Mike's Smoothie wheelcovers have a beautiful polished finish ...they're like a round mirror. Also known as baby moon or moon hubcaps (baby moons), this smoothie is a chromed solid steel moon wheel cover with a 360° steel retention system which is a continuous part of the hub cap (all one piece). So when you put these on your wheel, they will stay put. These are very solid, all steel caps, not the cheap flimsy variety found elsewhere! Perfect finishing touch to a classic car restoration or kustom car project; your wheels will never look better!
