Boveda 65% Two-Way Humidity Control Pack For Aging & Long-Term Storage in Large Plastic & Wood Boxes – Size 320 – Single – Moisture Absorber – Humidifier Pack – Individually Wrapped Hydration Packet

Depending on your humidor these last forever I get over a year out of one of these in my humidor

I've been using these for the past 10 years. Much better than propylene glycol or salt mixtures. If they start to feel crunchy, put a cup of water in your humidor, they'll fatten up as they soak up the extra humidity the water puts into the air. These will last forever if you treat them right.

Perfect price, perfectly fresh. Nothing else to say. Works as intended.

These big ones are the only way to go for me. I have two decent sized climate controlled humidors for my Cubans and I throw a couple of these in each one. I only have to replace them about once every 16-18 months. Major difference between these large size packs in the small ones. Just depends what size humidor you have, I do use the smaller size for my smaller wooden humidor and they work well too. I have to replace them every 6 months or so, partly because it's a wooden humidor and partly because the packs are so much smaller.Bovada's just last so much longer, are so much easier and distribute the humidity so much better than anything else I've tried (and I tried a number of things in the early days: cigar oasis, gel ect.) I've been using the Bovada's for years and for sometime now it's been a no-brainer.

Keeps my cigars at a constant humidity and in great smoking condition

These Size 320 Boveda Packs are a Perfect Match with my Cigar Coolers.

Works great in my humidor to keep cigars humidified properly. Simple to use, take out of plastic packages and place in humidor. When they get dry and crunchy, it’s time to change them out.

With Boveda you don’t have to mess with solutions or distilled water. Place this in your humidor and they last for a long time
