They heat up within 15-30 minutes and can be reactivated by exposing them to air and shaking again if the heat decreases.

The warmers are designed for single use and should be disposed of in regular garbage after use. While this means they are not reusable, the ingredients are environmentally safe. They are compact and portable, making them convenient for a variety of outdoor activities such as hunting, fishing, camping, and sporting events. The ultra-thin design and adhesive backing make them easy to apply, though users should note that they should not be applied directly to the skin for safety reasons.
