I love these packing cubes! I purchased them for a recent trip to Mexico and I was actually able to fit more into my suitcase when I used these than I could when I didn't use them. This allowed me to not have to check any luggage and I was able to breeze through security because my stuff was organized. Not to mention, I was able to find things on the other end because I bought various sizes and colors. I am usually a messy packer and am a zero on the OCD/Anal Retention scale, but these were fun to use, protected my clothes, and kept me organized. This was the first trip I've taken where I didn't have to hang out or iron my clothes before wearing them. Would recommend to anyone.
