6 mm Flobert plastic box made by Federal S.A. of San Luis, Argentina. This company started production in 1985 and continued the legacy of the defunct Spreafico factory that closed in the 70’s. They made shotshells, rimfire cartridges and primers.
SAS raised, copper case.
Can´t comment on these(never saw it),but labeling of the container is very poor ,“6 mm bullets”…at least cartuchos a bala cal 6 mm Flobert…,I had a box of their shotshells and were “roughly” made,no longer have any at hand,they were forwarded at the time to Don Steagall.
