BjjThe bags work, but they need to be just a little larger, especially the shoe bag and the laundry bag, when using for a week or two on vacation. However, they would probably work for a short 4 day weekend or business trip. I will have to wait and update about the durability after another trip with them.Zippers cheap and material very cheap broken the first time I tried to use it.8Pcs Packing Cubes for Suitcase Travel Luggage Organizer Bags with a Collapsible Cup, Travel Essentials Bags Set for Flying Luggage AccessoriesI've had packing cubes before and lost all of them! I've also ripped the type with mesh on them, and broken sewn in handles - I abuse my travel gear. Packing cubes are great - at first you'd think 'putting more stuff in my luggage sounds like less space!' but you're wrong. Stuffing a bunch of rolled up stuff in a zip cube then smashing that cube into your suitcase is way easier than trying to stuff sleeves and socks into the cracks of your suitcase as you sit on it. That's if you're like me and overpack.ANYWAY - the cubes themselves are nice, it's well made, and the fabric is a nice canvas and breathable. Is it bullet proof? No, the weakest point would be the zipper so I try to be gentle with zipping it while I pull it flat, but I do over stuff and it does hold up. It is inexpensive, but for the price I was able to abuse these quite a bit and they still look good. The toiletries bag is LINED with plastic (see my photo) so incase of small spills, it won't go everywhere, but I have yet to test this (luckily) - due to the sewing I don't think it would full contain like a bottle of water for example. I do like the variety included, the drawstring bag, the big cube, small cube (although I with there were 2 so that 2 small cubes could fit in the big cube). See my other photo (with my cat for size!) my suitcase is a carry on, and the big cube just fits in the side. The shoes bag is useful, the small zip i'm using in my carry on. Overall, I'm super happy with these, the pink is cute, it looks good, and it will definitely survive just long enough to be a good deal for the price.True to what is Advertised. I couldn’t believe how many cubes it comes with. The cubes are canvas and well made. I think you can fit more in a suitcase with packing cubes.Tip: be gentle with the zippers!This is a nice set for $20!these are so useful! they do not easily collapse and they look so much better in person. i'm so happy i found these. i'm about to go on a flight and i honestly didn't think i could ever find something to help me organize my stuff so well but this set is pure perfection. holds 8 outfits in the two larger sized bags but there's still a lot of them left to finish the job i need done. im extremely happy with theseI love using these to make my suitcases more organized. It's much easier to find what I'm looking for, and I can actually pack much more into a suitcase when I use these. They're sturdy and well made, I'm not sure why they include the folding cup, but it's there! The pieces are so lightweight they really don't add any weight to your suitcase, either.
