sterling silver poison box bracelet

this is a vintage sterling silver poison box bracelet. the bracelet itself is 925 stamped and so is the poison box. it’s very beautiful and you can store something small inside! it’s kind of like a locket but i think this kind is called “poison box” style as similar items were used in the old days to hide poison incase needed lol😭 please note: this is a family heirloom but i can guarantee it has never had poison inside. also the box is a little blackened so needs to be cleaned!
