This is an authentic pair of CHANEL Black Quilted CC Sunglasses 5150-B. The rims are rounded and over-sized and the lenses are grey. The arms are decorated with quilt, crystal Chanel CC logos and crystal charms scattered all over them. There is engraved Chanel logo inside the the widest part of the arms and on each of the lens. The right lens has an engraved number just next to the plastic CC logo.I have never used them so they are like new.They will come in box, with their quilted leather case and cleaning pouch.Unfortunately, I have lost their care booklet but I can enclose a copy of the original purchase receipt from the optician.
