The envelope is absolutely outrageous ... The visuals are really awesome! Cover fits perfectly is just made of silicone, but sits tighter than the cassette shells. The Gameboy optics is not cheap either printed on it but there are real rubber buttons, looks really awesome. The edges are also rounded as not in the cassette. I find the cassette even really awesome but the Gameboy fits slightly better. Case keeps perfectly well when to ramp up your pocket. Würd the envelope buy immediately! Incidentally, I have the white envelope bought because I also have a white iPhone. By "speaker slots" you can see the color and the iPhone camera cutout fits perfectly.
