Boveda's Humidification Packets are pre-formulated to a specific humidity level. These Boveda packets are amazingly accurate, keeping a constant humidity level within +/-2%, leaving no room for drastic fluctuations in moisture. The slim design allows you to store a packet virtually anywhere in your humidor without limiting the storage capacity, while eliminating the need for distilled water or PG solution. The more you, use the longer they last. Just remember to never mix different humidity level Boveda packets in one humidor or they will work against each other.
Recommended usage: 2 Boveda packets for every 50 cigars. Each Boveda packet lasts 2-4 months and when they start to feel dry and rigid, it's time to replace.
