Cyra asked:

Why do ironing products need to be stored in air-tight containers? Today there are many commercially available "warm packs." These hand and toe-warmers also use exothermic reactions. Why do these iron-containing products need to be stored in air-tight containers?

Reply:

because they work by iron combining with oxygen to make rust and heat
