Authentic, Real Gold Cartier glasses. MODEL NUMBER-COT80023 which is the registered trademark and design.number on case. Made in Paris-number 140 I think the style type is called "Piccadilly. Worn maybe 2-3 times. They are supposed to be sun-sentive non prescription slightly tinted glasses. The tint is very light grey almost non noticeable. These would be great for someone to buy, and then have the Cartier Company put in the lenses that you need. New these glasses retail for around $3,000-$2,500, this pair was bought on sale in Aspen, Colorado in 2006 to be used as sun glasses. Since they do not really get dark I could not use them (I have light blue eyes I need darker sunglasses). Very chic high quality pure gold finishing. These will be prefect as everyday glasses once you put in your own prescription glass any eyeglass shop can replace the lenses, but going directly to Cartier will of course keep them authentic but probably cost more (I think they charge $200 to replace glass depends on prescription of course). . Classic! Comes with, original box, second paper box, daytime glass carrying case, clean cloth, authentic booklet, and Cartier product book.
