This is one of those products that has you ask, "Why wasn't this ever invented before?" What a joy to pack everything...all my jackets, sweaters, skirts, blouses, and underwear have fit easily into the cubes provided. I then zipped everything flat, plunked the cubes in my suitcase and presto-chango! An immaculately packed suitcase!!! These cubes are especially useful if you have a lot of "loose" items and don't want them messing up your clothes as they slide around. In this case, I'm going back overseas after visiting my family in the US for a couple of weeks. I always take back all sorts of oddly shaped things and invariably, these items always mess up my clothes, no matter how carefully I've secured them. Now, no more! The cubes keep everything neat and protected. By the way, I must have checked out dozens of different models of packing cubes--the LeanTravel cubes are, in my opinion, the most stylish of the lot. I love the speckled gray fabric (with the red label). This is an attractive, high-quality product. Love it!
