A body warmer pad does one thing: it gets warm and stays warm for hours. These are single-use pads that begin heating the moment you open the packet and expose them to air, and they stick to the outside of your clothing so the warmth reaches you through the fabric.
The heat comes from a simple reaction. Iron powder inside the pad oxidises when it meets air, and that reaction releases heat steadily over hours rather than in a burst. No batteries, no cords, no microwave, nothing to charge.
The pads are thin enough to sit under a jumper without showing. People use them on the lower back, the stomach and between the shoulder blades, and they are a fixture of Japanese winter for commuting, outdoor events and unheated rooms. A pack of 10 covers a cold stretch or a trip. Kincho makes them in Japan under the Donto name.
One thing to be clear about: these stick to clothing and must never go directly against bare skin. That is not a preference, it is how you avoid a low-temperature burn.
