Do you have a picture of the lining?
In my opinion that is more than likely a fake,based on the Logo emblem. Here is an example of how Most MK Bag logo emblems are done.
I'm iffy about the logo as well. Also the handles where they connect to the bag don't look like what I'm used to. The fold is left exposed, but the authentic handles I've seen all have that piece that covers the fold and it makes the handle look solid.
