Vintage Christian Dior oversized sunglasses

I am consigning the sunglasses my older sister used to wear. They feature a 70s light brown Opti frame, and the lenses are a two-tone style with a slight blue tint. They were rarely used, so the condition is excellent. The case is worn out; if that bothers you, I can pack them in a different container. The price was set based on the price photo from the 8th foreign second-hand site. I am not accepting price offers. I will only proceed with a quick, quick transaction. Direct transaction only. I will cover the shipping cost.
