This Samsung RT21M6215SG 21.1 CuFt Top Freezer Refrigerator truly is one of a kind and unlike any other. Featuring FlexZone™, which is a versatile top door that can be a fridge or freezer, maximizing fresh food storage space. This allows you to expand your refrigerator space to chill your favorite beverages, snacks or party food. Unless you simply keep it as a freezer, but this is completely up to you. It also has Twin Cooling Plus, which maintains the humidity level of the refrigerator keeping foods fresher, longer. For example, dry freezer conditions for less freezer burn and better tasting foods.
