Each order comes with two individually packaged warmers (you can change the number ordered in your cart.) These are a great product to keep you toasty on the cold days. They produce heat for 6 hours or so and can be placed anywhere you need to toastify. The more you shake them the faster they will generate heat. You can choose to generate a good deal of heat for a shorter time period or a lesser amount of heat for a longer period. Use Little Hotties Warmers as directed on packages. Failure to follow the precautions listed below may result in serious injuries or burns. 1. Exposure of Little Hotties Warmers to free-flowing air may cause pouch to become very hot (up to 165°F), which could result in serious burns. Only use Little Hotties as directed.
2. Little Hotties Warmers should not be used under the following conditions: do not apply directly to the skin; do not use in shoes during vigorous activities such as running; do not use in shoes that have air ventilation holes, or in oxygen-rich environments.
3. Supervision is needed for use with the elderly, infants, children, people with sensitive skin, and for people that can't feel heat.
4. People with diabetes, frostbite, scars, open wounds, or circulatory problems should consult a physician before using the warmers.
5. Remove warmers immediately if they become uncomfortable or too hot.
6. Do not open pouch. Do not allow the contents to come in contact with eyes or mouth. If contact occurs, wash thoroughly with clean water.
