I was so excited to find these packing cubes because I didn't even know packing cubes existed!  However, when I received them I was disappointed. They are flat, flimsy and don't have the shape you see in the images on Amazon.  You have to fill them with clothes to get that shape but as soon as you start taking clothes out of them the shape collapses again.

However, and this is a big however, these packing cubes organized my suitcase in a way I never thought possible.  To unpack at the hotel all I had to do was pull out the packing cubes and put them in the appropriate drawers.  Before I left I repacked them with dirty clothes and that worked well.

Eventually I may try to find packing cubes with more substance but for now these will work!
