This Sardine Can Survival Kit contains 25 items to help you survive an emergency situation without losing your cool. You can probably guess the type of thing, fishing line, compass, ointment, matches, razor blade etc. It’s waterproof and airtight, so you can stash it in your vehicle and forget it, hopefully for ever. $12.99.
Since being well prepared is half the challenge, you’ll have a good head start with this kit. Put one in your car, boat, motorcycle, fishing vest, backpack, bike, emergency kit, etc. The kit includes one of each of the following items: non-aspirin pain reliever, adhesive bandage, alcohol prep pad, antibiotic ointment, book of matches, compass, chewing gum, sugar, salt, energy nugget, duct tape, fire starter cube, first aid instructions, fish hook & line, note paper, pencil, razor blade, safety pin, reflective signal surface, tea bag, waterproof bag, whistle, and wire clip.
While that kit is useful I find this one to be much more useful:

It is resealable so it is not a one use product.
