I am looking for a case which sort of fullfills the following criteria : 1. Lip to protect the camera and the screen. 2. Microfiber/soft lining inside to prevent scratching from dust. 3. Closed bottom. Am I asking for too much? Do I have options? I sometimes have to work in dusty evironments and the only thing that stops me from using normal spigen style cases is the fear of dust making it between the case and the phone and really scratching it up. Thanks!
