So I'm in the process of flattening out all of my original boxes and sorting through manuals to prepare for scanning. (just have to get a scanner

) I'm unsure what the best solution for storing the boxes in this way is... Would it be best to separate these in their own plastic (maybe sheet protectors) to keep them from rubbing against each other and causing wear? Perhaps in a binder of some sort? What kinds of solutions have you guys come up with in this sort of situation?
Maybe this question is a little OCD, but I want them to remain as pristine as they can be.
