Man duraseal was the shit. Buying back to school gear meant buying a roll of Lisa Frank or Space Jam Duraseal and laminating your books with it. It fucking ruled. I'm surprised it's not something I see in office supply stores anymore.
I'm old.
Edit: If it's because it's bad for the environment then that makes sense and I fully support ditching it.
It was a thing in Australia and I remember if you did it the schools wouldn't buy the books back. But it was damned if you do, damned if you don't, because they wouldn't buy back damaged books either.
