I bought a used car and someone had left these sunglasses in the car. Because of that I can’t absolutely guarantee authenticity but they seem real from my research. Left side: SPS04N 65(square)17 1BO-1A1 130 32 Right side: PRADA Made in Italy K CE Right upper lens inscription: BP11919344 Left upper lens inscription: PRADA These are used. There are light small scratches throughout the lenses that you can see when moving in the light. I can provide more photos or videos on request.
