These cigar-adapted, opaque boxes are dry boxes with added foam padding that keeps cigars from rattling about. Without a humidifier, the moisture level of the cigars that you enclose within the box remains unchanged, so long as they are not subjected to wild temperature swings. They do have a humidifier attached within the inside of the lid, so you can add moisture by adding a few drops of water to that. Or you can just toss in a humidifier packet of any sort. Very handy for traveling with cigars.
