If you dont use packing cubes, you aren't traveling right. They keep all of your clothes organized in different ways (tops in one, bottoms in another, etc. or you can organize by complete outfits!) and once you get to your destination, just open them up, fold the top under and everything is still organized and perfect. If you have kids, you can get a different color for each child as well as a different color for each parent. These specific cubes are special. LTKHome LTKTravel LTKFamily
