Hi,
I have the same bag but in the luggage color. Bought it a few years ago. Love the style but the leather on the back where it rubs with the clothes started falling apart within a few months. Very disappointed with that. And I didn't carry it all the time. Also if I get caught in the rain the bag turns grey. When I contacted MK they said this is normal wear and tear of the bag. I don't think this is supposed to happen within a few months of using it. Just curious to know if you have noticed anything similar? Maybe black does not show it as the luggage color. Love yours!
