This is a beautiful pair of authentic Chanel sunglasses in the style Black Square. They have black polarized lenses with UVA/UVB protection. They are large enough to block the sun very well. The style is universally flattering for all face shapes. I didn’t wear these a lot so there are no flaws except for a little bit of wear to the nose (they don’t look as shiny in this area but that is not noticeable). One arm moves a little loosely but it is not broken it has always been looser than the other. I loved the style but they were a little too big for me and weren’t tight enough on my face. (I have a small head and face.) The measurements are shown in the photos. They come with the box, tag, case, booklet, and dust cloth. I have the receipt shown but won’t be sending it due to personal info but you can see I bought them for $450 from the Chanel boutique. They are still listed for $450 on the Chanel website. Any questions please ask! Posh ambassador 2 One day shipper 5 star reviews ⭐️
