Just an FYI,

If you choose to store any of the survival bars that are sealed in foil or mylar wrappers, be sure to first put them individually inside ziploc bags.

A few years back I was doing an inspection of my vehicle kits and found the vibrations of the items were wearing holes in the bars. This even happened from bar rubbing against bar. All of them had worn through the foil (very small holes)and were tossed. After bagging the bars individually in Ziplocs, no more problems.

Good luck, TR
