This package contains 4 large Boveda packs in the relative humidity level of your choice. They are not individually overwrapped but they are in a high-barrier resealable zipper bag for storage until use.
60 gram Boveda provide hassle-free maintenance of full-size humidors and Humidor Bags. Every Boveda RH is accurate to +/- 1% of the RH level printed on the pack in an air tight environment, which humidors are not. It's common that the actual RH of your humidor will stabilize up to 5 points lower than the Boveda RH you're using, due to humidor and ambient dryness.
That's why we make Boveda in five different RH levels for tobacco applications: 65, 69, 72, 75 and 84 percent. So you can use the RH that achieves the cigar humidity level that you prefer.
And unlike distilled water and PG solutions with sponge/gel/crystals/beads that will impart unwanted flavors on your cigars, Boveda's reverse-osmosis membrane only releases pure water vapor and Boveda will never damage anything through direct contact.
Once you smoke a cigar stored with Boveda, you'll finally enjoy it exactly as the master blender intended.
Note: Do not mix Boveda RH levels within the same humidor, and do not use Boveda in the same humidor with other humidification products. They will fight against each other and reduce the efficiency of the Boveda.
