Burberry Leather Slingback Sandals

Condition: Good Sandals are in good condition. There’s discoloration throughout as pictured so please review carefully. It’s not super noticeable unless really closeup. I tried cleaning with water but nothing happens. Not sure if there’s another method to clear it up. I wore these probably 2 times so everything else is good no other damages or flaws. Irina model pictured wearing these stunning sandals. Dust bag & box included. Best offer wins!
