How to keep charcoal

Charcoal adsorbs various components such as moisture and odour in the air, and if such charcoal is ignited, it will suddenly give off the odour. Therefore, it must be stored without exposure to the air or humidity. 

Place charcoal in a sealed plastic bag and put it in a cardboard box, an airtight container the most ideal. The plastic bag also allows moisture to pass through to some extent, so it is good to put desiccant in it or a double bag it. If the storage condition is good, it can be used for many years.
