Each brick comes in a pack of 20 brown kraft paper and is not individually plastic wrapped.This product saves you the hassle and time of opening the packets when replacing your humidor every 2-3 months.We provide products with high cost performance by simple packaging.60g Boveda provides easy maintenance for full size humidor and humidor bags.All Boveda RH (relative humidity) are engineered to adjust to a precise unit of +/- 1% in harsh air environments.The actual RH (relative humidity) of the Hyundor is generally controlled at a lower humidity to 5 points than your Boveda RH (relative humidity) due to the humidor dry environment.For these reasons, we make all 6 Boveda products in 62%, 65%, 69%, 72%, 75%, 84% different RH levels.So you can use RH (relative humidity) according to your preferred humidity and cigar.In addition, PG (Propylene Glycol) solution with distilled water, sponge, gel, crystal, beads, etc. may cause undesirable flavor to the cigar, whereas Bovedas reverse osmosis membrane releases only pure water vapor and does no harm even if directly sprained.When you suck the cigar stored in Boveda, you will enjoy it like the cigar made by Blendmaster.
