GAP Black Leather Mules

Classic black leather mules with three quarter inch stacked heel by GAP. Size 8. There actually isn't a printed content tag anywhere on these- they look and feel like leather but I can't be 100% sure. Good used condition, do have a scuff on the left toe and some marks on the bottom soles, as well as a couple of faint creases. No other issues. Smoke-free home.
