This is an Hermès Chaine d'Ancre ring. It comes with the bag, box, care cloth (unused), instruction manual, certificate, and card – everything is included. Purchased at the Ginza store on April 9, 2024. I was recommended to buy it because it's very rare to find in the store, but I haven't used it much and have kept it in storage, so I'm selling it. If you're looking for one, please consider it.
