Cautions: Care should be taken if using Handwarmers elsewhere on your body. People with sensitive skin must use with caution. Avoid opening inner packet and getting contents into eyes; if this occurs wash immediately with fresh water. Keep out of reach of children under 6 years old. For external use only. Store in a cool dry place.

How they work: The warmers are activated by removing them from their protective airtight packaging to expose them to air. The blended ingredients of iron, salt and water, combined with the oxygen from the air, causes the rapid oxidisation of the iron particles. This reaction produces heat. The heating temperature and duration are controlled by the amount of air ventilation, which passes through the many tiny holes on the inner packets. The duration of the reaction is finite and the warmer should be disposed of after it has cooled.
