62% RH Level - 8 Gram Size - Two-Way Humidity Control Pack - Includes Replacement Indicator Cards - Food Storage & Herbs Moisture Balancer for Up to 1oz (Pack of 6)

I love these hydration packs. They seem to work better and for longer than the other ones I have used in the past. I have seen a noticeable diffference in a shorter amount of time when it comes to rehydrating flower or keeping already good flower fresh. I think I will stick with these and make them the only ones I use. 100 percent does everything it says!

Contrary to the AI answer to the question of how long it lasts — one year was the answer — if used to keep an eighth of an ounce of herbs fresh, I would say 1-3 months before you see the telltale blue color on the accompanying little card. There are many variables that affect their life, e.g., nature of substance, extant moisture, type of container, ambient temperature and humidity, etc. Regardless, it’s a good product.

These are a lifesaver!!

Please get the job done

I hope the quality remains the same now that these are made in Mexico, especially since they cost more than before. One concerning change is the removal of manufacturing codes on the product, making it impossible to determine how old these packs are. Given Amazon's inconsistent FIFO (First In, First Out) practices, they could be a few months or even a few years old. I’m assuming these are newer based on the "Made in Mexico" label, but there’s no way to be sure.

Seems to work good. Priced lower than other brands and similar results

…these are my favorite 2-way humidity packs now. Why? The indicator card that’s included with every pack. And these are individually wrapped. That’s important.

Great for keeping cannibis fresh and moist for over a year. I preroll and place them in a zip log small bag.
