subjected to changes in temperature and humidity that could cause condensation to form, and, since domestic kitchens vary a lot in both, the most stable environment - generally speaking - is the fridge. So, while they do not need to be refrigerated, the fridge can be a good place to store them. I keep mine on top of the fridge next to an air vent, and quite often use them when they're weeks out of date.
