Cute but not hinged at arms
Color: Porcini Tortoise, Size: 52-17-140
They were cute. I didn’t like that they weren’t hinged. They were harder to open and close. I didn’t look for this feature before I purchased.

Mis lentes son muy cómodos, y me gustan como lucen, vienen sin medidas yo los adecué con mi Optometrista.
Se aflojan con el tiempo, pero compré una pinza que ajusta los tornillos…realmente lucen como nuevos.
