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).
