I can't say enough as to how much I love these packing cubes, these have revolutionized how I pack for a trip. No more messy wrinkled clothing when you open your bag because everything is neatly organized and contained. I have given packing cubes to everyone in my family and they say the same thing about them. We never travel without them now. Also helps when it comes to TSA rooting thru your clothing because it makes it easier for them to see and feel what is in the packing cube, therefore your clothes are not all re-arranged and stuffed back into the luggage!
