here are some pics of my recent purchase, 65% HF beads. so far there great. holding around 68% which is what i really wanted.
in the first pic you see the finished product. just about 2oz of beads in the two little black humidifiers.
the last pic, is simple about 3oz of beads in a mesh bag, and there will be 25 cohiba robustos soon in that humidor!
