This is a HERMES Sac à Dépêches 27. The material is Taurillon Clemence and the color is black. The stamp is J. It also comes with the often-missing clochette and keys. If you would like to see the item, I can meet you in Tokyo. If you have the clochette remade at Hermes, you will need to leave your bag for several months and it will cost 40,000-50,000 yen.
