Black faux suede chunky heels

Very stylish heels with a chunky heel. I got them from Nasty Gal and never wore them out; they're in excellent condition. The brand is Koi footwear, and it indicates the size is 5, but I ordered a 7 and they fit me well as a 7.5 👍 The back is very cute, has a key-hole cut out. I'm open to reasonable offers!
