These packing cubes are very convenient to keep clothes separate, organized and folded properly inside the suitcase. The set includes three different sizes that are great for different purposes. I use the smallest one for my underwear, socks , etc. the medium for shirts, and the big one for jeans, sweaters, etc. I got the eggplant colorant it is very cute. The material is fantastic because it's light and allows the clothes to have some ventilation. I recommend this product to any frequent traveler.
