6 self inflating sand bags (BA2)

These are brand new and came from my father's house. They are all sewn up, so I am unable to show you, but they have a good amount of gel inside. It's squishy, but I can't get it out to show you, or I will ruin the bag
condition as new but may be a bit dusty I think he said they needed water to inflate, and they are single-use military ones.
