The protective case is made of a combination of two complementary materials shockabsorbing TPU and reinforcing polycarbonate. Thanks to the twopart design, the case provides reliable protection of your device from both scratches and falls. The model uses Air Cushion Corners technology, which increases the damping of the phone's corners during a fall. The case is slim, wellsuited, fully functional and does not restrict access to the device's interface and ports. <> In addition, the CS model has a special credit card slot that provides maximum convenience without sacrificing style and security quality. Slim Armor CS has undergone suitability tests and received MIL STD 810G516.6 certification, which means it has fallen 26 times from a height of 2 meters. All Spigen products are tested for abrasion resistance and precise fit to ensure a high quality case.
