  • GOOD TO GO
Color: Black Size: 12x15.5 100PC
Nice quality. Self adhesive works great. Be careful laying it down because wherever you put it, it's staying, no second chances which is exactly what I want in a mailer. That way I know it's not going to come apart half way to the destination. Tremendous value. Nice and thick material. Very happy with this ... show more

  • Does its job especially for small businesses shipments!
Color: Black Size: 12x15.5 100PC
It wasn't as thin, but I'd still choose to use two mailers for shipping purposes. There were a couple of bags that had some tears (from snags I think, it wasn't a hole, it was just like a wrinkle), but I was surprised I got an extra 2 mailers in the bunch! I'm not as worried about the tears anyway because the important thing for me was to waterproof my packages. And I bet this will do the job! Will definitely order again. I just hoped I got a different color because the black one (I realized) looked like a garbage bag. LOL. It was really black. I'm giving it four stars, because of the quality of some mailers, but I recommend it because it's going to do its job pretty well, and for a cheap price too!!! ... show more

  • Great for small businesses!
Color: Black Size: 12x15.5 100PC
These little shippers have saved me a ton in shipping costs. The adhesion strip is a little short, but a piece of tape can fix that. They’re much thicker than the cheaper options available, but they’re susceptible to warping if stretched at all and will tear if mishandled.
