Great for mailing books to minimize damage. Nice and sturdy for shipping and mailing. Very pleased with shipping and product costs. Thanks

Easy to use, protects lightweight items, cuts shipping costs. Arrived in timely manner.

Great item and a great deal.Helps me trmedously with my shipping. Waterproof and flexable!

These are the best price I found, 50 per case was more than I initially needed, however, the cost was less than cases of 25 that I had found elsewhere. They met my criteria as being plain white, unadorned with printed address blocks and other printing, capable of accepting my ink jet printed self-stick labels and packing tape, and allowing folding over on itself. I have used two so far, and time will tell if they will hold up in the mail, as I use them to ship books. I am very satisfied.
