Heat it in your home microwave for 1 to 2 minutes and apply it to cold areas. Be careful not to overheat it in the microwave, as the contents may burn. If used properly, it can last for about 2 years. Recommended warming points are the sacrum, the lower abdomen (dantian), and other areas such as the back of the neck and around the eyes. It can be used in various places. One size is approximately 21.5 cm x 11.5 cm. This is the price for a set of two. #WarmthActivation
