They are non bio.
Way more resilient than bio BBs.
Should still be good.
They are still good, but most field will want you to use bio BBs now. Theses will break down in a few months, especially if exposed to humidity.
I have a bag of MetalTech .25s in black (seems like no one makes good, black BBs anymore). They are not made anymore since 2005 and I got the bag from a guy that stopped playing in 1999... fed a bunch in my very picky Katana and never had a jam.
