Paper safes with wall mount

[Bjørn Joachimsen]

I am looking for paper safes (12x16" & 16x20") with wall mount (for vertical storage). Any recommendations?

I have seen some film safes for x-ray films that would work, although I would be concerned about paper curl.

I saw some a few years ago at a surplus equipment liquidator and in a condemned hospital building.
