100 ct Plastic 9x12 Self-seal Poly Mailers. Tear-proof, Water-resistant and Postage-saving Lightweight Plastic Shipping Envelopes/Bags.

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!

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! 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.

I like these just fine, and they work well!My only issue is that I ordered BLACK, and was sent white, and although disappointed, I needed them “yesterday”, so I didn’t have time to wait to return and reorder, so I’m just using what I was sent!

Overall, exactly what I was looking for- a solution for shipping lightweight packages by first class mail. Price was awesome! They keep items dry and clean- very sturdy. they are self sealing, with a plastic strip that covers this "sticky" area, The strip easily peels off. While I appreciate this feature I have had one frustration with this: "The strip easily peels off".- They come packed together quite tightly and sometimes when I go to grab one, that protective plastic strip on the envelope below gets caught and comes with it.... have to be really careful separating one from the stack. Aside from that, they are the perfect inexpensive shipping solution for me that I will continue to buy.

I use these to ship product out on ebay. They are sturdy but light. Great quality. Perfect size for magazines. I was using larger one from the samem company for shirts but found that when I created a nice paper fold shirts also fit well in this size. I will definitely purchase again when I run out.

I bought these bags to try out. I am constantly sending homemade items to my family. I need a bag that is sturdy and will hold up to the Post office and UPS. Have sent 3 now and they arrived undamaged (rare). I use bubble bag inserts for some items and they fit nicely in these bags. Thanks for a great product for a super price!

Way thinner than another brand. Offer very little strength or protection. I’m doubling them and they are still flimsier than the other brand.
