Silicone Prism Case - crystal protection. The Prism Case silicone case is made from a modern type of rubberized silicone, thermoplastic elastomer. This silicone is safe for human health and does not adversely affect the environment. Constantly using a phone in the case does not cause it to overheat, unlike cheaper silicones. The Prism Case silicone is a transparent, resilient, and sufficiently flexible case. Over time, it does not stretch or become cloudy. The inner rear panel features a crystal structure. The case itself is not glossy, but the crystal facets create an effect of sparkle, color transitions, and shine in the sun. The dimensions of the Prism Case exactly match the contours of the phone and its functional ports. Small borders around the camera, speakers, flash, and touch screen effectively protect the phone from drops and impacts. The volume and sleep buttons are covered, providing complete protection from water and dust. The ports are open and easily accessible. The Prism Case silicone is thin and lightweight. During
