Nearly everyone has an old 2AA mini-mag or two laying around, stuck in a drawer, glovebox, etc not being used.
Well get it out and put it back to work with this "cap"
Simply remove the head, bulb and insert, screw this cap on.
You now have a watertight container that can be used for many different tasks!
Carry extra batteries, pills, cash, etc.
You can always convert it back to a flashlight if you decide.
Made of 6061 T6 Aluminum.
