My pipe rack's humidor uses a thin, rectangular AZTEC Clay Moisturizer. I'm looking for a couple more, but haven't been able to find any sources for them, even after searching the web. Can someone help? Thanks.
I know exactly what you mean, and I haven't seen one for many, many years. I think they are no longer being made. They do have the disk ones that are about the diameter of a quarter, and about a quarter inch high, and they work reasonably well.
AZTEC was the way go years ago. Like ravkesef I haven't seen them in years. The "Humidor Store" has them as small bricks. They are an inch thick. humidorstore.com
