Edit: Note, there are plenty of superficially similar boxes which are not acid-free archival quality - so make sure to find the right version!
because 3 ring binders need them to be 3 ring binders. all of my neg pages just happen to have 3 holes that line up with the rings? coincidence, I think not.
