I had previously ordered the set of packing cubes (small, medium, large). The small is great for socks (I can pack 10 pairs of socks in this cube). The medium is great for underwear (I can pack 10 pairs in this cube). The large is great for pull over shirts (able to pack 12 XL shirts). When I have to live out of a suitcase for travel, I find these cubes excellent for keeping my stuff organize. I liked so much that ordered an extra medium cube. Unfortunately, the large cube was out of stock but will purchase another when it is back in stock.
