## Description

desertcart.com : NextDayLabels #9 Double Window Check Envelopes - 500 Pack Ready-Seal Security Tinted Envelopes for QuickBooks, Sage 100, Blackbaud Checks - Self-Sealing Laser-Compatible - Made in USA : Office Products

Review: Excellent product at a third of the price - highly recommend - We use a proprietary software system for churches (widely used in the US). We were told (of course) that only their envelopes would fit their checks. After buying one box for about $120 after shipping I determined never to do that again. I spent quite a bit of time measuring and comparing different alternatives, and decided to take a shot with these - I figured with "guaranteed to fit" I couldn't lose. I had previously had great luck with different #10 double-window envelopes from desertcart. These are excellent! Well made and they appear to be sturdy enough. The adhesive works very well, I have not had to reinforce it. I was most concerned about the window placement - would they fit properly without a lot of fiddling and re-positioning the print fields? They fit our checks perfectly with no drama. The window placement is about perfect. In fact, better than the "proprietary" models, these don't reveal anything on the memo line, but the addresses are perfectly visible. As others have noted, they are just large enough to also accommodate return correspondence such as a tri-fold letter-size invoice copy. Not so large that the check floats around, obscuring the address. I am very happy with these and I am spreading the word to others!

### ⭐⭐⭐⭐⭐ Perfect fit!
*by B***A on January 10, 2026*

These envelopes worked perfectly! The perfect fit for my checks

### ⭐⭐⭐⭐⭐ Easy to use, and good quality.
*by H***D on July 1, 2016*

These envelopes are exactly what I needed for my Quickbooks checks. They are less expensive than the ones you get from Intuit or even Quill. My last batch of envelopes from a different supplier had poor adhesive. These self-adhesive envelopes are really good. Simply lift the flap, fold the lip over, and press to seal. I haven't had a bad envelope yet.
