Great product to use with the Food Saver vacuum seal bags. My sister uses them when she is storing dehydrated food under a vacuum in mason jars.

I purchased these almost exactly a year ago to put on my windowsills. We had just moved to Missouri, and I was concerned about the humidity factor and the temperature changes from outside to inside. I hate scrubbing mold buildup off my windowsills from condensation, and had the idea to try these after watching how much condensation build up there was already on our windows in mid-October. When they arrived, I wiped down the windowsill with a diluted bleach solution, and threw a few of these on the sills. I have not had any mold issues at all! I absolutely love them, and recommend this solution to anyone sick of dealing with mold accumulation from condensation (a lazy and or busy womens solution to this minor household first-world problem).

I use these in my acoustic guitar case. They have helped keep down moisture

I never knew I needed these till I started sprouted and they work great and help my sports last a good week without rotting in the fridge ! I’m sure they would work great if you meal prep and want to keep you cut up veggies more fresh for the week as well.

Bought these to put in my ammo cans to keep everything dry. So far so good. I live in Florida where humidity is high, especially during hurricane season when power goes out and everything gets damp. So, these should help keep everything dry.

Love these for storing winter/summer clothing. Keeps them from getting musty. Also great to put in closets and dresser draws

Was sent in a fast and exactly what I needed.

Just over a year ago I purchased these Silica Packs to help protect my stored ammo. If the silica inside these pack stayed clear then my ammo should be moisture free. That is unless these packs didn’t work as advertised in which case seeing clear silica would indicate a “False Positive” for the presence of moisture. Quite by accident I learned these packs actually DO work as advertised and they are VERY effective in the indication and absorption of moisture. Please see Photo One followed by Photo Two for details.

I only warn you not to let them get submerged as they will completely fall apart. Other than that they work great!
