Please contact me off list. I would be concerned about storing acetate tape in them as I'm suspicious that the traditional cardboard box is functioning something like a molecular sieve and absorbing some of the acetic acid outgassing/effluent from the tapes and retarding any vinegar syndrome. No skill/time to prove it, but it seems to be part of the puzzle as to why sepmag film tracks are deteriorating while older 1/4" magnetic tapes are not. Another part of the puzzle is the thickness. I would be careful. The venting would help, of course, but it might also promote drying-out of the acetate tapes. I don't know what the issues are (if any) with polyester or PVC tapes).
