VacYaYa50 Grams (20 Packs) Food Grade Moisture Absorbing Silica Gel Dehumidifier Sachets for Storage, Dehydrating Silica Gel Packs No Harmness to Moisture

This helps reduce moisture really well. I place them in the refrigerator to try and cut down on the humidity inside. One suggestion, if you're going to place these in the refrigerator, get one of the larger sizes. These are just too small.

These limit moisture in dehydrated foods to help shelf stability. I put them in a jar after the conditioning time is complete. Then, I vacuum seal them in my jars.

Decent size and seems like good quality. Hopefully it will keep moisture out of my safe

Very nice like the size and it does the job highly recommend them

Bought these for my ammo can an for the safe work great good value for the money
