Some time ago I received a SR that I purchased and when it arrived it was wrapped in some kind of paper inside the coffin box. It had the look and feel of something like waxed paper, but it was not the kind you use in the kitchen. Can someone advise what this paper likely was and where can I purchase some? I am assuming it was acid free paper. And on that note, is kitchen variety waxed paper suitable to wrap razors in for longer term storage?
