Store premium smokes in the largest heavy-duty plastic bag exclusively for cigars. Engineered 3X stronger than a food storage bag, this tough, laminated humidor bag provides the same protective moisture barrier as a tupperdor. Conditions new cigars before you transfer them to a traditional humidor. Makes for a convenient, affordable second humidor when that perfect box deal rolls around. Properly ages a growing cigar collection. Keeps cigars in perfect smoking condition wherever you’re headed—herfing, boating, skiing, golfing or camping. Preserves souvenir cigars you buy on vacation. (FYI: The humidity level in an airplane is a desert-dry 20%.) As soon as you take cigars out of a humidor, fluctuating humidity levels cause cigars to lose essential oils and flavors and affect smokability. Preserve the expert blend of tobaccos and perfectly balanced filler, binder and wrapper. No matter the outside conditions, the patented Boveda uses all natural salt and water to ensure an exact 69% Relative Humidity (RH) inside this high-tech humidor bag. Its press-to-close zip top creates an airtight seal. A simple touch test will let you know when it’s time to replace Boveda—it will feel crunchy and rigid. Note: Do not mix different Boveda RH levels within the same humidor. And do not use Boveda in the same humidor with other humidification products because they will fight against each other and reduce the efficiency of Boveda.
