Cigar Keeper Humidification Tube

Cigar Keeper Humidification Tubes forego the traditional foam inserts and instead employ a quantity of small, water-absorbent crystals to maintain the desired humidity level in your humidor. The crystals last twice as long as traditional green foam and are naturally bacteria and mold resistant to eliminate the worry of tainting your collection with unwanted substances. Simply pour distilled water into the tube and place it in your humidor for up to a month of adequate humidity.
