Bag of sachets has been sealed and vacuumed. I opened it up and inspected the packages and found none had been exposed to moisture. I currently use about 10/50 and the rest is sealed in a bag and stored in my humidity controlled safe. All in all the best value for money. These pouches are oversized and perfect for tossing in a toolbox, long-term storage of ammo in an airtight container, or anywhere storing something that could rust or spoil from moisture.
