Bought this from the Cartier online store in Sept 2020. Selling because I gained some weight after having kids and need a bigger size. Please know your size before purchasing! You can also see a size guide on Cartier’s website. 18K yellow gold (750/1000). Width: 6.2 mm (for size 17). I like the cuff because you can take it on and off easily without dealing with a screwdriver. Stacks well with other bracelets. Has hairline scratches which is inevitable with real gold. Comes with full set, including box, bag, authenticity card, cleaning kit, travel pouch. I even have the original wax seals and ribbon! Retails for $5300 brand new! Only Reasonable offers considered. Buy from a trusted posh ambassador- Check my reviews! Be sure to check out other items I have for sale. Bundle and save!! Also posh authenticates all items over $500 for free!
