I took a risk with Cossino as I had never heard of them, but I was looking for hexagonal glasses that would be small and not dominate my face, and these fit that niche so well. I love how I look in them, and I even love how they hang from my shirts when I am inside, especially white or light colored shirts. The orange hew they have is just the kind of vibe I was looking for this summer.
As for the "sunglasses" part, they're not the most sun blocking glasses in the world, but they do the job fine enough. The materials used for the lenses and frame are worth the low 100s if we're being fair, and that's roughly what I bought the glasses at. Originally, I was going to give this 3 or 4 star, as I was getting a little cold when I first open them out of the box and feeling them out for the first time, but after having worn them for about a week, I am actually quite pleased with my purchase so I think it deserves 5. Maybe if I had bought them at $200, I think I'd reduce my score to 4 because that does get rather pricey, but at $125, definitely 5.
