## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Heavyweight?
  

*by M***. on Reviewed in the United States on June 25, 2015*

Probably my fault but I thought "heavyweight" would mean heavier than usual.  My dumb!  However, I am finding these envelopes satisfactory.

### ⭐⭐⭐ 







  
  
    Three Stars
  

*by G***M on Reviewed in the United States on October 25, 2014*

Not as thick or stiff feeling as I thought it would be?

### ⭐⭐⭐⭐⭐ 







  
  
    never buying them from the store again
  

*by D***S on Reviewed in the United States on December 22, 2014*

I can't believe how cheap these were.  I've spent way more on these types of envelopes before for basically the same thing.
