Cheap low quality!!!
I don't recommend buying these sunglasses from neff, yes they may look cool but they're extremely cheap and made with very low quality plastic. I bought two pairs and returned them both the next day! If you do buy these I'm guaranteeing they will break on you less than three month after you own them! Not to mention the pairs I got the bows were crooked, the glasses were dirty that wouldn't come off, and the lenses were scratched.
So just say no and spend a lil more money on a higher quality pair of sunglasses, trust me it'll be worth it.
