Kate Spade shoulder bag

Used a handful of times. Bottom is not perfectly flat as seen in picture. There is a white mark on the front as shown in the last picture - can barely see it in some lights. I imagine could be treated by the right technique. Can be used as shoulder bag or cross body (hits me at my hip on cross body, I am 5’5”). 10in wide x 7in height x 2in in depth. Length of 22in from apex of strap to top of bag.
