If you're not too bothered about appreance would you not be better making a cheap plastic tupperdor and adding some thin slices of spanish cedar from old cigar boxes or tubo's to absorb/ balance the moisture?
I made one once using an old plastic tub and a calibratred reptile hygrometer. It may not have looked great (in my sock drawer!) but it held the humidity level perfect, it never drifted more than a few percent after being opened.
