These packing cubes worked pretty much as expected; they just looked a little smaller than I thought they'd be until I packed them in my carry-on bag. There's probably a good design reason the zippered entry into the bag is only on 2 sides, but it would be easier to pack if the cube opened on 3 sides. I rolled my clothes, packed into the cube, and zipped all the zippers. When unpacked, clothes were mostly wrinkle free, but a dress to be worn to a wedding needed a little pressing. I think I'll get better at packing the right amount into each cube. Over packing most likely caused a little wrinkling and it definitely made it harder to zip the compression zipper. Overall, the cubes are reasonably priced and easy to use, help keep the travel bag organized, and help cut down on wrinkling (with some practice). With use, I'll see how sturdy they are.
