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