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 had a plasticky thing that you had to neatly fold around the inside of the cover of the book. there was also one that was self adhesive, you pulled the thing from the backing sheet and then stuck it to your book.
and yes as soon as you got your books you had to wrap them up
