X-Doria Engage is a very thin case. It has a unique texture that will protect the back and sides of your Samsung and protect you from scratches and shocks. The case is made from two materials. The flexible TPU is on the edges and the hard polycarbon on the back. This provides effective, compatible protection against scratches and damage. The unique texture of the entire back cover of the case gives it a unique character without blocking the phone itself. Perfectly cut buttons and phone ports ensure trouble-free use of all its functionality. Smooth, glossy surface highlights the unusual design of the phone.
