At CES today, Otterbox introduced a new series of iPhone cases that are some of OtterBox's most minimalist yet. The one-piece Symmetry case is available in a number of different colors and graphic designs for both the iPhone 5s and 5c. The cases leave the front of the iPhone completely exposed, but they protect the sides and back of the device -- a very popular style of case. OtterBox also has the Commuter and Reflex series cases, but those use multiple pieces rather than the one-piece design of the Symmetry.
