I don't think it's silly at all! I think *my* getting a box was silly since I'm not using it. I keep my bags in their dust bags in the drawers of a large dresser. I live in a Victorian that's pathetically low on closet space.
It's also a good idea to replace all the inside stuffing with acid free tissue. Have I done that yet? No, but I plan to.
doreenjoy, some of my BV's came stuffed with a silver metallic tissue. That's definitely not acid free. Some are stuffed with packing paper similar to what movers use and that's not AF. And I have serious doubts about the white tissue in the others. AF tissue can get pricey. I use it in needlework conservation. I did find a couple of online sources (wedding gown conservation suppliers) that offered it in bulk at a decent price.
