Grabber body warmer

No embers, absolutely odorless. Essential components are iron powder, activated carbon, and salt. As soon as this mixture comes into contact with oxygen, the iron powder oxidizes and heat is released. The contained substances are all biodegradable, meaning Grabber warmers do not burden the environment. After activation, heat is released for about 6 hours (body warmers about 12 hours). Temperature development: hand and body warmers about 57 to 70 °C, foot warmers about 38 to 42 °C. With adhesive surface. Content: 1 piece
