Don't let your good cigars go bad just because you're short on storage. With Boveda’s unique 2-way humidity control pack, you get a perfect smoke every time. Our 69%, 60-gram pack is intended for customers who already own a humidor or other storage device and simply need the humidification, and it’s accurate to plus or minus 1% in an airtight environment. The RH (relative humidity) in traditional humidors will often stabilize as much as 5 points lower than the Boveda RH system. And unlike water and PG solutions with sponges/gel/crystals/beads that will impart unwanted flavors on your cigars, Boveda's reverse-osmosis membrane only releases pure water vapor without any direct contact.
