We're seeing a lot of clear rubber and plastic cases in the early days of the iPhone 5c, and iSkin is joining in with Flex ($25). Coming in clear with one of three different patterns, or black with a carbon fiber-looking finish, it's made of a TPU-style flexible plastic. The design is pretty straightforward, and includes button protection. iSkin includes a microfiber cloth and pre-moistened cleaning swab with the case.
