This kit is designed to be a 72-hour kit. It is designed to be small and portable, but also to be effective in providing for the Survival “Rule of Threes.” The basic kit is enclosed in an Altoids tin, wrapped with 10 feet of 550 parachute cord. Note the 3/32″ diameter hole drilled in the upper right hand corner of the tin. This kit provides for shelter preparation, fire making, water storage and treatment, signaling capability, basic medical needs and food procurement. [via] Link. I think Altoids should sell these in the check out lanes at grocery stores (with mints too).
