I feel like I now need more of these sets with more color options for a even more organized packing experience.

So I got these because I am a chronic over packer and I needed to pack in JUST a carry on for my upcoming 5 day trip.  I was super nervous that I wouldn't be able to do it, and I really didn't understand how a packing cube could help me, but I had read all the reviews of people swearing by them, so I figured I would give them a try and just return them if I hated them. Well, I was able to do it, and I have never felt more organized on a trip!  The best part was that everything fit the same way on the way home.  The packing cubes helped me give each item a place, Which helped me:
1.  Fit all of my items in a carry on
2.  Stay organized
3.  Know where each item was in my suitcase and save time
4.  Minimize the "rummage" of looking for an item in the bottom
One set fits perfectly in a carry on bag.  I want other sets in other colors to use for longer trips where I may pack more or have multiple destinataions or if I am sharing a bag with someone (color code per destination/person)
