Superb box is there for provenance …I should imagine it’s pretty rare to get a box like this now…They will cost you a pound each anywhere and not be as original and good as these …read the label NP brass ..if you want me to explain then don’t buy them …🤣🤣🤣ideal for rubbing to produce an aged (patina) 58 in total@at .50p each that’s a bargain..please remember measurements are on box only to mention there imperial
