Used these in my carry on suitcase, only the largest cube and the medium cube fit inside. They are thin and light which is good. Fit all of my clothing pieces great and zipped up fine. Zipper feels a little cheap but didn't have any problems. Will definitely continue to use these packing cubes as I was able to pack much more than I could have packed without them. I ordered the blue color and they look exactly as shown in picture. Great buy for the price!
