### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for QuickBooks invoices
  

*by C***W on Reviewed in the United States on March 21, 2015*

These are perfect for QuickBooks invoices.  Plenty of room for several sheets of paper and the address fields line up perfectly.  No more licking envelopes, no more pull strips to dispose of, and the seal is good and strong.  I will definitely be buying these in the future.Note:  these are not the ones to use for sending out QuickBooks checks.  They really need to go out in the #9 envelopes.

    Great for mailing checks
  

*by J***O on Reviewed in the United States on February 22, 2018*

Use #9 envelopes often.  The security ink on the inside does not bleed as it does in other brands.  The folding self seal is a wonderful, time-saving feature.  It works well for mailing checks.

*by H***N on Reviewed in the United States on December 31, 2015*

Purchased for QuickBooks. They work, but it is obvious they were not made for QuickBooks as the windows do not line up well with words on checks or statements.
