As Promised . . . lightweight, easy to see what is where. I suggest a light or bright color in a black-lined suitcase. Filled them firmly, not as tight as humanly possible. No seams gave way, zippers were fine. I'm an organized packer but these helped at my destination, just popped 'em in a drawer, no frantic searching for things, like items were together. I folded carefully, no need to hang things immediately. Didn't need all the cubes on this trip, and the shoe thing - eh. Shoes are better around the perimeter with soles facing outward or bagged individually bags w/ items stuffed inside. I used it for something else.
