I bought this product to take on a trip. I could only use 2 of the 4 mesh zipped bags. The 2 largest ones had zipper problems even without anything in them. Zippers are very cheap, the other 2 will not last long. Do not waste your money.
First— these are NOT compression cubes. They are your regular packing cubes. Two of the zippers arrived broken, however, it was too late for me to return them because my flight was the next day. There is not a compression factor at all with these cubes. Cute color, bad quality.
I'm not sure what's wrong was happening, but at the end of the trip, I took allthing out of them,repacked my luggage,and sure, I was able to pack everything more tighter. Great for organizing, but don't expect them to create more space for you
