Anthropologie Summer Night Green Stacked Heel Sandals

Anthropologie Summer Night Green Stacked Heel Sandals. Size 8.5. Adjustable ankle strap. Open toe. There's a small nick on one of them located on the green area on the side of the ankle/foot. There's a close up pic of it. It's possible it's just dirt or something. I tried to remove it, but didn't want to actually scratch it or nick if it's not a nick. See pics for condition and details. Smoke free home.
