Instant Cold Compress
This instant cold pack has a wide variety of uses, including muscle strains, bumps, bruises. It also helps sooth sunburn and minor burns. The endothermic reaction that powers the cold pack means that there is no refrigeration required, allowing you to store the pack in a standard first aid kit without special temperature regulation equipment. The added convenience of the instant cold compress ensures that you will be able to use it without preparation in the event of an emergency. This also makes it far more portable than a conventional ice pack. Note that the cold pack is disposable; do not attempt to refreeze the instant cold compress. Do not puncture.
