Kris are you planing on including a mirror in you survival tins? I keep a thin one made from the laminate they make unbreakable mirrors on airliners from. Airline mechanic have used it for years for inspection mirrors ect. It even comes with a nice protective film. I've made quite a few to give a way to friends. The protective film also makes a good place to store a piece of duct tape in your kit. If you want I'll send you one to try. I made up the last batch in about 15 minutes on a shear.
