I find a lot of joy in brand-new notebooks, but there's no doubt that they can be wasteful. Rocketbook makes several reusable notebooks, planners, and accessories like flashcards. Take notes with an erasable Pilot Frixion Pen (one should come with whichever item you buy), scan photos to the Rocketbook app, and erase the whole thing with the damp microfiber cloth. The app is designed to keep everything organized and easily send things off to Google Drive, Evernote, OneNote, and a handful of other options.
The paper isn't as nice to write on as regular paper, but it's made to withstand a damp cloth. Can you write in any notebook with a pencil or erasable pen, take photos, and erase it? Yes absolutely, but that will eventually ruin the integrity of the paper. It all depends on your budget and habits. If I took a ton of notes every day, I'd probably want really good paper, but I like that one notebook can last as long as you take care of it. I stuck with the black pen it came with, but some people buy colorful Frixions for more organized notes.
