Cute and was exactly as expected
It is exactly as shown. I have a very small head and these did not slip down my nose. The lens is large as it says in the description but I like the coverage from the sun. Great price!

Nice!!
These lenses are very nice and protect you well from the sun. They are dark enough to be able to use when the sun is very strong in the afternoon. It comes with its mandarin case, it has the logo outside and its sleeve also with its cleaning wipe. I always loved it, I always drive them in the car.

Great sunglasses
These sunglasses look great if you have round face and a low bridge nose like me. Thick and sturdy. The only dislike is they tend to slide when they are on the top of my head. Cute case and a drawstring bag inside the box. Can’t beat the price either.
