I have two of those that I repurposed for overflow troop cigars.
They worked far better for holding humidity than the great big honkin marine igloo cooler I have, and I used very few beads.
We have 5 or 6 coolers, for some odd reason. Those cubes are the ones we use when we take a cooler anywhere. They've just been better all around for everything.
They're cheap, too.
