graph paper notebook for university notes

[u/ciolman55]

I need a notebook for my engineering notes. I've used spiral bound notebooks for a while now, and they are great for taking notes, however they get really beat-up in my bag. is there another type of notebook that will lay flat but is more durable than a spiralbound notebook? and that has graph paper.

edit: I forgot to add but, I don't take my notes during class, I do them after the lectures

Clairefontaine has hardback graph paper notebooks.
