They're sold as a complete front/back kit and will cover the entire front and the chrome back of the iPod.
Please note that after installation you will be able to tell there's a coating on the device (as it is a thicker vinyl material). These are thick enough to take the abuse that would have ended up marring your iPod's finish and are designed to be a low-cost alternative to the thick rubber cases while retaining compatibility with third-party accessories like docking stations and holsters.
