About two months ago I ordered a nice 12-16 stick travel humidor. It was a very nice hand-rubbed cherry wood box, but it was sold without a humidification system. I asked about available systems from the order clerk, and she recommended your drymistat tube. I was a little skeptical about such a cheap and unconventional system, but I took her advice. When my order arrived, I became even more doubtful - it was too simple. Just add TAP water and throw it in? It had to be for people who didn't really care about their cigars. I don't want to take up half your day with my letter, so I'll conclude. I've ordered one for my 40 stick box and two for my 75 piece antique. I plan to leave the elegant hum. system in my antique, but only for show. Drymistat will be my only humidification system for now on.
