HOW THEY WORK:

N-FERNO Warming Packs literally “run on air”. Each soft, lightweight pouch contains a mixture of iron powder, water, vermiculite, cellulose, activated carbon and salt. Once the outer package is opened, an oxidation process takes place which causes a safe, natural reaction to release heat. N-FERNO Warming Packs utilize the same technology as used by the National Ski Patrol, explorers of the Arctic and Antarctica, and military forces around the world. Over one billion Warming Packs are used each year in Japan alone.

REUSABLE:

If warming time is not completely exhausted, N-FERNO warming action can be preserved for SEVERAL DAYS by packing them in an airtight container, such as a zip-seal polybag. N-FERNO accessories are packaged in their own reusable heat action preserving zip seal polybags, for your convenience.
