Mine came that way, too, and I agree that it's probably something reacting inside the leather slip pouch. My Fusion 2 had zero manufacturing residue present anywhere on the device. I always clean received items (and those I ship out lol), but it likely wouldn't have needed it. Heating or polish pads will bring it back nicely.
It did take me aback a little bit when it arrived, so maybe they should do something to keep it from happening.
