Posted on reddit but figured I'd share here too. Not sure what these really are, best guess is Personna USA's. I do know they were made prior to 1989 because that's when the label was discontinued. The price was a steal, each box a dozen packs for $5. They don't slide out of the dispenser, the oil has glued them down so I had to use a pair of pliers to crack it open. The blister pack is very yellow, and I've noticed they still have the faint smell of oil. Guess I'll try one in the near future.
