PureFlow 72-Hour Survival Kit (60 in 1)

Just don't know what the small tube on a key ring is for. It screws open and looks like maybe could store a battery, but AA and AAA won't fit. Can you tell me. I did have to oil a couple items, pretty stiff to open. Loved everything In the kit.

I love the whole package! Everything you need in case of emergencies.

It’s a great little kit with lots of items to help out at an emergency. It’s great to keep on hands just in case an emergency hits.
