I have no idea but while I was reading your question this popped in my head.

What if you were to use a food saver to vacuum seal, say a box at a time, and leave a little air in there with a boveda pack? If they really are air tight then you won't lose any humidity. The Boveda would get the cigars to the RH that you want and keep them there. I imagine that 1 pack would last for years.

Again I have never even thought about this and would like to hear some other thoughts on this.
