The Symmetry Series is an elegant and precisely constructed protective case for your smartphone, and its one-piece design makes it easy to install. The construction, made from two materials, makes the Symmetry Series one of the thinnest and most protective cases in its class, built to military standard Mil-Spec. The raised, textured edge helps secure the touchscreen better, while the material and honeycomb structure protect the smartphone from impacts and bumps. A wide range of patterns and colors offers users customization options. The sleek, simple Symmetry Series provides the style you want and the protection you need. Tested by us. Designed for you.
