EZ-Magnetic Chuck Key Holder

I'm well into my eighth decade but I can't say that I've heard of a pocket protector before. Its use is obvious from the name and I am guessing that it is a leather slip-in liner. Maybe it is a US term? Do you have a photo?

Leather !? Be still my heart. We could only dream of such luxury.

Type "pocket protector" into Google images and you'll get plenty of pictures of the device itself and genuine nerds modeling them.

I do believe they're a Usonian invention, probably originated as give-aways at tool shows.

Back in the 70s if you had a pocket protector, black frame glasses taped with white surgical tape and a white shirt that advertised everything you'd eaten for the last four days you could repel girls from distances as great as 150 yards.
