Heat therapy is clinically-proven to relieve neck & shoulder aches and pains. NeckHeat is designed to be "split-able" so that you can use it exactly where you need it most.
As skin at the neck & shoulder area tends to be more sensitive, we have calibrated NeckHeat to release a slightly less heat as compared to MenstruHeat.
Simply tear open the packaging and once NeckHeat is exposed to air, it will heat up within 5-10 minutes.
