I used these to ship out a backpack and it arrived in perfect condition I used two bags instead of one to make sure if it ripped it would be fine. I think it would have been okay with only 1 but I also worry about shipping and it being damaged then or cut on something so double bagging is my recommendation. Good for soft items being shipped. Very good bag.First time ordering Green. These arenas described, appropriate thickness, quality.They’re very thin yet hold up so nicely.These are good mailers. The size is nice for my small business products and the color bright. Sturdy and the glue works great. I've had zero problems using them in the mail for packages sent all over the world.Adhession is good ..I’m always skeptical about buying polymailers off the internet because you never know what you’re going to get. Although these seem pretty thin, they are actually very sturdy. The adhesive on these things are amazing!! Will continue to use these for shipping! (:Big enough for shoes boxes and wider itemsI use for shipping clothes I sell. Easy seal and love the purple.They are way too thin for the size, Almost see through. Waste of money!these are the thickness, toughness, look, and feel of a cheap garbage bag. Not a strong poly mailer as advertised. Absolutely embarrassing to mail products in this cheap junk.Buen producto. Lo volveré a comprarVery thin mailer for 24”x 24” size. Total wastage of money need to use clear tape on top as it was tearing from everywhere.
