You do get more mint for your money with a converted mint that's for sure. It's the mints without holes I feel sorry for. They just get forgotten.
If anyone is interested I've actually got some holes for a set of these left over from a previous project.not sure how many I've got I'll have to check later.
Whats there country of origin? I've heard mints from some countries are thinner and don't last as long (in the mouth of course)
Post-war German mints have always been metric, while British ones were imperial....it all went a bit menthol after decimalization.
