The Mobilize Gelly Case is made of high quality TPU and falls under the category of soft cases. TPU, also known as Thermoplastic Polyurethanes, is a relatively soft material and therefore very flexible. It therefore fits well around your device. The Gelly cases are made of high quality and offer good abrasion resistance. Because the case has raised edges, the display of your device is well protected against possible scratches and stains.
