Michael Kors Manhattan Medium Contrast-Trim order

Product Name: Michael Kors Manhattan Medium Contrast-Trim order
This Manhattan satchel is 100% Italian leather with a neon contrast trim. It includes flip-lock fastening which provides effortless access to belongings. The interior includes two pockets while there is also a front exterior pocket that allows for a phone or items to be accessed easily. The Manhattan includes an neon trimmed adjustable strap (19'-21') order that is removable. I have used this purse no more than twice, yet developed a small black mark on the top of the purse. (shown in pictures) I am unaware if this is removable in fear of damaging the beautiful purse further. It has been hard to let this go because the quality and look is striking!.
