Kate Spade leather satchel bag

I purchased this purse to be my every day work bag about 4 years ago. It fit my small laptop perfectly and got lots of use for a couple of years! However I don’t use it often anymore so selling. There are some discolorations on the bag as seen in the pictures. Inside particularly lots of pen marks. One inner pocket also needs to be re sewn. I have not attempted to clean any part of the bag. One of my favorite things about this for work is the shoulder strap that comes on/off!
