It’s still just a box with a tightly fitted lid. It should work, but I can see the concern with moisture if the inside of the box is cool, and you open it while the surrounding air is warm and humid. I use a box sold for pet food storage. Essentially giant Tupperware the key is there is no insulation. But you should be able to make it work, as long as you keep condensation prevention in mind.
I have other non-beer ingredients that I buy in bulk, vacuum seal and freeze. I usually pull the bags out of the freezer and let them come to room temp before I open them. No condensation problems.
