Using this survival kit is easy. The 7 - in - 1 tool can be used for navigation, checking temperature, lighting up the dark, making a loud sound to attract attention, and more. The signal mirror can help you send signals during the day. The fishing kit can be used if you need to catch fish for food. When using the flint with striker or matches, be careful to avoid starting an accidental fire. Store the kit in a cool, dry place to keep it in good condition. Make sure to check the contents regularly, especially the perishable items like matches, and replace them if needed. Also, keep the plastic bottle tightly closed to maintain the waterproof feature.
