For those fly-by visits to the refrigerator, the Door-in-Door feature allows you to get in and get out providing easy access to beverages and snacks. Only LG Door-in-Door models include bonus door bins for added organization and storage. Extend Food Freshness with the ColdSaver Panel acts like a barrier keeping cold air in where it matters most - in the inside - giving you peace of mind that food will stay fresh longer. It reduces cold air loss by up to 47% to help keep food fresher longer. The LG SpacePlus Ice System is on the inside door, freeing up valuable space in the fresh food shelf compartments. More space means you can store more food.
