Authentic Michael Kors Tote Purse Bag

Black Michael Kors tote/purse/bag. There is a white scuff mark on the front in a few spots (look at picture). I have not tried to get it off because I’m not quite sure what it is and how to remove without hurting the leather. It’s a great bag and has a lot of space. Pocket for phone and a large zippered pocket inside too.
