This was given to me by a friend today, who had visited a recent Mardi Gras parade. His girlfriend found it while randomly scavenging around.
It originally had a red rubber band on it, but that ended up cut and lost, hence the regular rubber band to keep it closed. Thankfully it was never used though.
I'll agree that it was unlikely. Someone probably had it in a jacket pocket or something they used when hunting last and it fell out. Sucks for them, that's probably not cheap.
Happened to kids I went to high school with. One guy I knew had to call out sick because he forgot he had a few boxes of ammo in the back of his truck from hunting over there weekend. Pulled in to school, saw the boxes, and realized he didn't have time to get home and back before lunch. So he just noped out rather than get in all the trouble.
