I purchased one of these in each color, kept two and shared two with someone else. I was amazed at how much these little packers held! I have two "pet peeves" with traveling. One is keeping my suitcase organized. The other is dealing with dirty clothes. I used these on a short trip, and my suitcase was always neat - a welcome change from what I normally experience! One color held the clean clothes, and I used the other for my dirty clothes. It worked so well, I just may have to come back for another set for longer trips!
These are a tremendous help with packing and unpacking. I have used them twice for week-long trips. I was able to pack many more items than I expected, and clothes didn't get as wrinkled as when I just pack them loose in the suitcase. I also think they will help your suitcase stay neat when TSA inspects it. Unpacking is also much easier--you can just put the packers in drawers without unloading them, and everything stays neat and separated. I ordered a second set for my husband.
