Chestnut bow flats

New. Never worn. The sole is intact. However, while taking the pics I noticed on the heel subtle stains that look like drops of something that got on it. I can’t tell what it is. I didn’t attempt to clean it for I wanted to be transparent about it. Doesn’t feel oily. It’s just there. Got these ages ago and then my feet outgrew them and I just can’t wear flat shoes anyway. Maybe the heel spots can be cleaned. They’re like a caramel or chestnut colour. Bundle to save! All offers are welcome.
