If I imagined myself a mobster attempting to puzzle the problems of arrangement (and if these were waterproof and odor proof), there would have been many a hilarious scene made with these in some blockbuster movie. But, alas, I do not arrange parts in cases.

I am merely a traveler and my quest is to pack as much in as little space as possible, while leaving enough room to bring back the welcome gifts of booze from distant lands. These cubes are so essential that I cannot possibly express their virtues in a deserving manner.

You can roll your clothes tight, bundle them in, fold them like oragami and arrange them in pleasing fashion. You will get more in your case than you would without these cubes. They protect your precious bottles and allow the curious drones to search your stuff without destroying your sense of privacy too badly. These even come in various colors so you can pack a riot in your case, quite possibly brightening the day of any dour-faced TSA agent.

I do have to take off 1 star, however. I fear for the zippers...
