This reusable, non-toxic heat pack is safe even for kids and pets. Depending on the pack's exposure, activation, and use, it will provide heat for approximately 45 minutes to 2 hours.
- Maximum temperature is 54°C.
- Contains water, a stainless steel disc, and food-grade ingredients.
- Activate by snapping the stainless steel disc and then, as it changes color, knead it to maximize heat and make it last.
- To reuse, simply boil the pack for approximately 5 minutes. (Microwaving not recommended).
- Be sure not to let your Reusable Heater Pack freeze. Sub-zero temperatures will permanently affect the internal components, meaning no more toasty heat.
