Guess zebra sling back pumps size 6

Guess zebra sling back peep toe pumps, canvas material. 1 inch platform and 4.75 inch heel. Worn once or twice. No marks on the outside. However, on the heel a bit of material came off when trying to take sticker off and there is a brown color noticeable from the glue. These are both not noticeable when wearing because they are on the inside. This can be seen in the last pic.
