2-Way Humidity Control Pack - Preserve Flavor & Control Humidity at 62% RH - Moisture Absorber for Herbs, Spices & More - 4 Gram (Pack of 20)

Excellent. Works as advertised.

I had no idea these things existed and when I found them it shocked me that I could find so many uses for them. Being able to control the humidity of anything is great. Whether it's the humidity of cigars, spices, herbs, your guitar. Or what ever else you need to have Humidity control for. I had always seen the silica packs that keep things from getting too humid, but I've never seen it the other way. So far these are very durable and high quality, they definitely been a great value for my money. There is no complication to their use, you literally take one and place it in whatever container with whatever product you're trying to maintain its humidity, after you put in the humidity control pack you just put in their little square piece of paper with a DOT on it and that will tell you when the humidity pack has run out and you need to replace it. It's that simple. For me it has kept spices that would normally dry out in a month or 2, in a jar, it now keeps them fresh, it seems almost indefinitely. I have shown these to guests I have had over, and they were just as surprised to see it, they had never heard of such a thing either.

I bought these awesome little packets. I put them in my little container that I have rolled joints in to keep them fresh and not dried out and burning my lungs when I smoke it and I also put it in my bags of weed. I love these things they have the little indicator that shows you when it needs to be replaced. Awesome idea!! These are better than the popular brand that is charging way too much money hands-down these are my new go to❤️

Would be great if the indicator was integrated into the humidity control pack.

Works well.

These last me longer than the boveda brand and they're cheaper.

Tested for 48 hours with a hygrometer and it's averaging 62.5% humidity. My home humidity averages low 40s. I placed 1 pack in the jar with my flower and 1 in the Mason jar with my flower. See photo.

I have bought several of these. I really like them. I personally think they are over priced. They work like they are supposed to.
