No embers - absolutely odorless. Essential components are iron dust, activated carbon and salt. As soon as this mixture comes into contact with oxygen, the iron dust oxidizes and heat is released. The substances contained are all biodegradable, i.e. GRABBER WARMERS do not pollute the environment. After activation, heat is released for many hours.
Runs with air!
The warmer is activated by a chemical reaction with oxygen from the air (the ambient temperature should not be below 1-2 ° Celsius). For optimal heat generation, it is recommended to remove the warmer from the packaging a few minutes before use and leave it at room temperature.
