These are fine for storage while you are deployed. I have a small 2oz bag of Shilala beads in mine. You should have some type of humidification device (beads, water pillow, etc) to ensure they don't "dry out".
If you have any major concerns, PM a brother here (who just currently deployed) by the name of Tobii3 who uses these and larger versions religiously. He can provide you with all the "facts" about these being "battle tested".
Stay safe and thanks for your service!!
