MCM klara medium shoulder bag

MCM klara medium shoulder bag. gray, leather, authentic. worth $950 I believe. it was a gift from my x, therefore I am going to part with it and make some money! I wore it for about one week so it has a little wear but it really is brand new. the inside can be cleaned up which I will probably do before I sell it because it only has a couple pen marks and some "purse dirt".. aka paper, lint and probably random crumbs or whatever purses fill up with. hoping to get about $500 but will definitely take the best offer!
