...My recommendation for the acrylic jar, because there is so little space in there, is a Boveda 65% 2-way pack. You could also go with a very small tube of beads, which are also 2-way humidifiers, from either HCMbeads.com or heartfelt.com, but, you will lose the space for one to two cigars by putting that tube in there.
That's okay, Adam; He'll be in a coolerdor before he finishes those Ghurkas.
