This is a STICK HEATER that you can easily bring anywhere and anytime. When you shake or rub the stick, it radiates and warms your hands. The maximum temperature, when heated, is 40°C, and it lasts for 48hours. After using it completely, you can exchange the used powder for new one. (powder : the mix of active carbon, salt, and iron.) Like making fire in the primitive age, let's making warm. Have fun winter with stick heater!
