Unfortunately, fake. The writing on the inside is much too embossed and “stamped” in vs a genuine Apple leather case.
On an Apple leather case, it’s almost difficult to read the text in the microfiber since it’s so subtly placed on it.
Also, the grain looks like PU Leather and the buttons do not look authentic and aren’t sitting in a subtle “cut” in the leather. Also the mute switch cutout looks sloppy.
