These were actually bought as a present for a friend. I already have several sets of assorted sizes that I've been using for several years. Packing clothes in cubes (especially if you roll rather than fold) minimizes creases, and it's so easy to find the garment you want. On a recent trip to India, where we were never in one place more than three nights and in many places just one night, I simply lifted out the appropriate cube, took out what I wanted, and put the cube back. Meantime, my travel companion was still rooting around and unfolding and refolding.
