Heat Pax BOX of 40- 20 Hour Body Warmers
HEAT PAX™ will only produce heat when it has oxygen present. You simply insert the Heat Pax into specially designed pockets and it generates heat for up to 20 hours. Heating can be stopped at any time by resealing the inserts in an airtight container or plastic bag.
