SUNPOP 3 Pcs Packing Cubes Travel Space Saver Zip Storage Bags Single Compartment Luggage Organizer (Black)

I received this set as a free review sample. I own a few sets of packing cubes from other brands in various colors and sizes. My observation is that there are premium ones and less quality ones (I own both kinds). This set is definitely premium.One thing that sets premium ones apart is the zippers. Each cube in this set has sturdy zippers that have two pull tabs. They are not prone to coming off the tracks like the lower quality cubes. Another thing is the stitching, which on these is close and straight. Note that the stitching is on the inside of the cubes, and along hem lines.A feature that I especially like is there are handles across the tops of each cube. To be honest, for their intended purpose I am not sure how useful their are, but for the way I use these cubes they are a nice feature. I organize and store cables and other odds and ends in all of the cube sets that I own. The open mesh allows me to see at a glance if a particular cube has instrument, microphone or speaker cables, or small electronic gizmos that I use on stage. And the construction of these cubes are why I rated them so highly, because cables in the larger cube weigh in at close to eight pounds. This particular brand is sturdy enough to hold them without splitting like lesser cubes are apt to do.Finally, for folks who are actually using these for their intended purpose, they are labeled with a graphic of what each cube is designed to hold: outer wear, underwear and the such. Not that it needs those since the open mesh reveals what is actually inside, but I thought it was a nice touch displaying attention to detail.If you are a traveler these will allow you to pack neatly and actually maximize space in carry-on baggage. If you are a camper or just need bags to organize gear this set is excellent. If you are a musician, this is perfect for organizing cables. I actually use an  On Stage KSB6500 Keyboard Stand Bag  to hold cubes with specific cable types, and the arrangement works perfectly.
