Chanel 5143 Black White sunglasses

I had eye surgery and my vision has declined, so I can only wear prescription sunglasses. I purchased two pairs of sunglasses and still have the boxes and guarantee cards for both. However, both guarantee cards are blank, and the numbers on the back of the boxes are different. What I can say with certainty is that I bought them at the Chanel store in Caesars Palace Las Vegas, and each pair of sunglasses has a serial number engraved on it. I can guarantee they are 100% authentic. Experience timeless elegance with this Chanel black quilted leather bag, featuring the iconic diamond pattern and a structured design for a sophisticated look.
