The Symmetry Series is an elegant and accurately designed protective case for your smartphone and is easy to install due to its one-piece construction. The two-material construction makes the Symmetry series one of the thinnest and best protective covers in its class (built to the MIL-SPEC military standard). The raised, profiled edge provides better protection for the touch screen, while the material and honeycomb structure inside protect the phone from impact and shock. A wide range of patterns and colours offer the user personalisation options. The flat, simple Symmetry Series offers the style you want and the protection you need. Tested by us. Developed for them.
