Review: 10/10 - Works great, exactly like expected! Good quality and stiff enough for documents etc. Seals exactly like it's supposed to. It's not so stiff that it won't bend though - so if you need something absolutely too stiff to bend this won't be it, this is more flexible. Works great for what I need though, and comes with do not bend stickers, so I've never had an issue with it.
Review: Great envelopes - Bought these for my business. They are very sturdy and seal well. Very good value for the cost.

### ⭐⭐⭐⭐⭐ Great envelopes
*by S***5 on December 29, 2025*

Bought these for my business. They are very sturdy and seal well. Very good value for the cost.

### ⭐⭐⭐⭐⭐ Turned Out to be GREAT Mailers
*by I***N on June 20, 2024*

Was initially skeptical that these were adequately strong mailers. When they first arrived, they seemed a little too flimsy. But after 3 restocks and 300 successful mailings later, these have changed my mind. The adhesive strip, while thin, is adequately strong to survive multiple days/weeks of travel, even from the mainland to Hawaii and overseas military bases. The feedback from the recipients has been consistently great. We do add an additional 1oz piece of cardboard inside for additional strength since the 1oz difference rarely changes our mailing rates. All in all great value for the price of 100 mailers + "Do not bend" stickers. zmybcpack has adequately convinced me to be a reliable brand.
