I work in the travel industry and travel a lot. I am on or near a beach at least every 3-6 weeks depending on how much i am stressed out.These bags are great for those who travel, i was in Aruba and Costa Rica recently, both had late flight out and my hotel was near a beach, sooo.... of course, I wanted to soak up as many sun rays and get some more beautiful ocean swim in before i headed back to the airport to return to work :(These were GREAT! they kept my last-minute wet beach clothes from soaking up all my other clothes in my suitcase and stinking them up! If you have ever put wet or damp beach clothes in your suitcase after a vacay you know well that it will smell really bad and not only that, but it will have your suitcase smelling bad for a while to come.This bag was sturdy and the locking zip was very durable, they did not burst open in my suitcase. I also like these bags for my big bottle of shampoo and body wash, they were also perfect for keeping my dirty shoes and sneakers isolated and not touching my work clothes along with my wet beach slippers & my damp beach towels.All-in-all a great solution for beach & pool goers and travelers who always are looking for nifty solutions to simple complex travel dilemmas lolIt is perfect size for my little phonics writing booklets for my Preschool class.Well made bags, great for clothesAwesome product, very happy, will order again.I love the thickness of these bags but several bags had small holes on the side of the seams causing a small leak and therefore unusable for my purpose. Disappointed in this.I got these to put quilting projects in! They hold the fabric yardage and the cut pieces, keeping the entire project together. I did not want flimsy bags, so these are perfect. I like them so much I ordered some in other sizes. My husband saw them and said wow, great for moving and putting auto parts in! I have a feeling he will be stealing my bags and I will be ordering more very soon.I use these while traveling and they are great. I can organize all the small things and not worry about liquids leaking all over the bag if for some reason a bottle leaks. I wouldn't say they are puncture proof but a nice thickness for a plastic bag. And the zip close holds great as well.These are perfect for putting your sweaters away for the summer with a little lavender packet or a few "mothballs". They are heavier than I expected and a very nice size. These are the kind you save when you buy something expensive to reuse around the house.
