Great reusable hot pack
I purposely bought this hot pack for my menstrual discomfort. It was easy to use. Initially, it stays hot/warm for about 20 minutes. My boyfriend helped me reheat the hot pack. He made sure not to bring the water to a full boil because he did not want the plastic to melt off. The hot pack becomes a gel and stays pretty hot for a while. I can continue to use it until the gel cools of completely.
