### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Best self sealing envelopes I have used to date
  

*by M***L on Reviewed in the United States on August 2, 2020*

We usually buy envelopes like this from Walmart, but we have been sending out more letters during COVID-19 and I guess others have as well because Walmart is out most of the time.  We bought these and I won't go back to the Walmart ones again.  They were perfect, good security and not see through and the seal was super great.  If you made a mistake sealing it, then you have to basically destroy it to open because you cannot open from the seam again.  The best and great price for 500.

    Envelopes
  

*by R***Y on Reviewed in the United States on September 5, 2024*

These #10 envelopes are perfectly designed with peel away sticky strips to seal them shut.  The sides are opaque providing needed security.  This is the third box I have purchased.

    Great Value!
  

*by J***. on Reviewed in the United States on April 21, 2021*

I had not waste.  All envelopes had great adhesion and were of sufficient quality for the job.  Some reviews note adhesion issues - again, I had none and used all 500 of them on a mailing.
