Chanel sunglasses for retail women

Product Name: Chanel sunglasses for retail women
These are really nice sunglasses but I don't know if they are real chanel they have no made in or serial #. All they have is " CHANEL" on right lens as seen in pictures. They are made very well and the jewelled arms are amazing. Also the most comfortable glasses I ever wore and they are in great condition because i took really good care of them. They were given to me as a gift back in the early 80's. I believe. I really love them but I really need money. Feel free to ask any questions. I am retail trying to raise money so I will take offers. Thanks for looking at my listings.
