These two rounds are not from my collection. All I know is that they are apparently made by a company named Safety First. They were made before 2008 (when I first photographed them) but have a WIN 9mm LUGER headstamp so they are not very old. The white round has a snapped primer but the black round looks like it has a live primer.
I tried the internet, but “Safety First” gave me nothing relevant. Has anyone seen these or know anything about Safety First???
