Set of 2 warming/cooling pads. I received these at the maternity hospital after giving birth, but I didn't use them and have been storing them at home. They remain soft whether cooled or warmed. They conform to the body's complex curves. Reusable. Although they are maternity goods, they can be used for various purposes such as headaches, eye strain, toothaches, fever reduction, lower back chills, stiff shoulders, sore throats, etc. ■Features ● Designed to fit the body's complex curves.
