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.
We did it because over here the textbooks were reused the next year. I dunno if books are even used in school anymore or if everything's on a computer now.
