QUAY Icy 51mm Gradient Square Sunglasses | Nordstromrack。Quay Incognito is a popular oversized shield-style sunglass model. They are a LEGACY model and are no longer stocked by Quay. Gradient lenses provide a suave update for flat-top shades that offer stylish sun protection. These glasses are in very good pre-loved condition. They were a gift that was purchased from Nordstrom but were not really my style so they were not worn very much. Per the Nordstrom Website: 56mm bridge with 17mm lens width 100% UV Protection Polycarbonate Lenses Plastic/Metal I do not have a cover for them.
