Review on Dot Large Packing Cubes: The Ultimate Travel Accessories for Efficient Packing and Organizing by Brenda Mitchell

For some reason after looking at the photos I expected them to have a certain shape. I thought maybe they are soft, lined or something like a cube? nope They don't have a shape - they're a flexible, thin piece of flat nylon with zippers. I appreciate the light weight, but the material is so thin you can see through it if it bothers you. I packed our clothes. into these for our emergency bags so they do their job, but a couple of these aren't fully wrapped (just so these cubes can get structure) and I'm afraid they'll crumple if the bag moves at all and crush everything inside. They're ok and the price was pretty good so I'll keep them. But if you're looking for something more permanent, this probably isn't it. Edited 9/26/20 to add: After that I bought some more packing cubes and decided to try the Revain Basics brand. In my opinion they are much better! They are just as light but the material is a bit thicker and they have a shape/structure. I would buy them again, not this one.
