Toewarmer

NEVERCOLD toe warmers are used inside footwear as a comfortable and efficient source of extra heat. The heating pad has a sticker surface that keeps it in place between the sock and the sole of the shoe. NEVERCOLD toe warmers are small cushioned bags made of a porous material with a mixture of iron powder, activated carbon and salt inside. When the sales package surrounding the bag is opened, the mixture is allowed to react with air, causing heat to begin to form. The reaction continues on its own for 9 hours. The production of heat can be interrupted by moving the bag to an oxygen-free place, e.g. an airtight minigrip bag, so that the use of the heater can be continued later.
