fwiw--I don't think you'll scratch or abrade a negative as easily with a interleaving type--simple fold over--sleeve or a "fold-lock" type sleeve. Even one made out of polypropylene which will cost about a third of what a Dupont archival Polyester (mylar D) sleeve will. Simply because you are inserting the neg into this and folding it shut--no sliding it in & out. the colection at work--we have some old 8x10s that have been stored for a long time in a very simple way. They used those tall Hollinger boxes, and had about 25 or so negs in hollinger folders inside with a blucore type board spacer to keep them upright. Every few years, on a schedule, they switch those boxes out for new ones and get rid of the old ones as they age....
it doesn't get much better than that really for low-paranoia negative storage. Good paper--you can't go wrong...
