These women's Kleo metal-plastic shield sunglasses are unique because of the way their frame is structured. Other sunglasses have one continuous frame that extends to the pieces that go over the ears. The piece that's supposed to connect the arms to the lenses is usually a solid piece of plastic. The way that the arms are connected to the lenses is different in terms of design. Everything on the sunglasses is thinner than what you would expect from a pair of shades. You have to pay special attention to these sunglasses. The way that you take care of them will make sure that they will last as long as possible.
