The LG Door-In-Door feature is for people who really like doors, especially refrigerator doors. Essentially, it is a door within a door. Like a secret compartment for food, the standard fridge door opens up again to reveal more storage, almost as if it were a mini refrigerator itself. Keeping this secretive quality in mind, the LG Door-In-Door feature could easily be used by those who are trying to hide food from others.
A unique concept, the LG Door-In-Door feature is not actually meant for that. Instead, it was created to avoid unnecessarily letting out cool air from the rest of the fridge. Working in conjunction with the super-capacity three door french door refrigerator, it is capable of storing 31 square feet of food items.
