Boveda69% Two-Way Humidity Control Packs For Plastic and Wood Containers Size 60 – 4 Pack – Moisture Absorbers – Humidifier Packs – Hydration Packets in Resealable Bag

Over the (many) years, I have tried all the "usual" humidification devices; they work, more or less, but require frequent attention too keep the RH where it needs to be. Boveda packs are pre-charged, never messy, and last for months in a tight-sealing humidor -- especially storage humidors that aren't opened very often. I prefer the 69% RH formul;a. Using very tight-sealing lucite jar humidors for my "daily" smokes,, a single Boveda can last six months or longer even when the humidor is opened a few times a day. I use Boveda in traveldors too ... and even in plastic zipper bags when I need temporary storage when my other humidors are full. Here's a tip: it's possible to recharge a partially depleted Boveda by storing in a zipper bad with a source of humidity, as long as you do so before the Boveda gets too dry

Easy way to keep cigars fresh, just feel the bag when it's dried out just replace it. Seems like they last a long time, depending on the placement of the humidor they can last up to a year sometimes

Best and easiest option for a humidor. A "set it and forget it" product. I replace them every few months as recommended, however, I've never seen the humidity drop, so they could probably outperform the recommended change date. The bags themself are very thick, so they can even be crammed into a travel humidor without breaking.

No better way to keep cigars fresh long term other than a nice humidor. I have one of their bags with two of these in there and have kept my cigars fresh for years, literally.

These work great in my guitar cases

I purchased this item for my cigar humidors to keep my cigars fresh. They bring the humidity up quickly. My only complaint is that they do have a short life. Just so you know, these can be recharged but it takes a while.

No issues fit in my humidor

I use for my flower in an airtight container and it keeps it at a constant relative humidity. Remember, terpenes are your friend, so preserve them with these.
