I have several FAK's. I have 1 for each vehicle(4), 1 for my purse and a big one for home. For the ones in the vehicles I used a zippered day planner. I took out the calendars and added badge protectors, like for pictures only stronger. I have a carbiner on the zipper in case I need to just snap it to my belt loop. I was surprised at how many things they hold. And everything is easy to get to. Like flipping through a book. Actually they are more like survival kits because they pretty much have everything in them, and I'm still adding things. The one for the house is just a $5.00 plastic tool box from Wal Mart (kind of big). I have stocked it over the period of about 6 months. None of them were very expensive and I have tailored them to suit my needs.
