Inquiry (采购产品): Question on acid-free paper Hello - I've recently purchased many 4x6 refill pockets, Item #899790, to catalog my postal first day covers. They are marked as MBI, a division of MCS Industries. I'm wondering if the white paper that comes within the inserts (used to separate) is acid-free, safe for my postal covers for many years to come.
