    Great Envelopes For Saving Money And Protecting Contents
  

*by C***A on Reviewed in the United States on August 8, 2016*

The envelopes were exactly what I needed for mailing out heavy manuscripts.  It will save on postage, protect the papers because it's plastic, and it won't tear easily at all, just what I wanted.  I couldn't be more tickled if I'd swallowed a pink feather duster.  Oh-one caveat; be sure that you have Sharpie or similar pens with which to address your envelopes, or, have mailing labels on hand because you can't write with a normal pen on these envelopes.  You can buy either right here on Amazon!  What a surprise!

*by R***E on Reviewed in the United States on March 5, 2015*

These Poly Mailers is a fantastic idea. These mailers are exactly the size I need. I haven't used these yet, but I will use them soon. These mailers seem to be much better than other plastic mailers I have used. These mailers seem to be stronger, and not near as likely to tear; and yet they are lighter than the paper mailers of the same size. This will save ne postage costs! Thank you.

    These are lightweight and perfect for shipping
  

*by L***. on Reviewed in the United States on October 27, 2016*

These are lightweight and perfect for shipping! I have been going through my closet to sell things on eBay and have not had any issues with these bags. Although I purchased 100, these are thin enough (yet strong) that they are very easy to store. I will definitely purchase these again in the future.
