Works great. I wanted the jars to be larger or as large as they appear in the picture. But they are pretty small. And quite expensive. But they work if you have large humidors with a large stock of valuable cigars. A can of this size holds about 100 cigars. So take it from there. Once you receive them, remove the top, fill with distilled water, then replace the cap with a black breathable top and you're done. Just put it in your humidor. Again, the total number of humidors depends on the size of the humidor. Although Xikar also sells them as tubes, they are easier to use. Hope I helped someone. If so, a "yes" would be welcome for me.
