#9 Security Envelopes are just as good and cost way less than the ones from Office Depot. They work well with our QuickBooks invoices but not so much with the QuickBooks checks - you need a smaller envelope for those.

I was using envelopes with double gummed flaps. Terrible. The top flap did not cover the bottom gumming completely and look a mess. These are fantastic. Windows fit statement addresses perfectly, the back comes up higher to the flap, the paper is smoother and thicker. Better quality, better fit, great value.

I had been using these envelopes for 3 years. They fit all of my correspondence for our address and vendor addresses.I was down to my last 25 envelopes and the 3 different envelopes we have are not the correct size. I am so glad Sam's Club still provides them, so I ordered for another 3 years.

Work great with my QB invoices and statements

These window envelopes fit our QuickBook checks perfectly. I appreciate the 500 quantity carton. The adhesive seal makes for a quick assembly for mail.

Envelopes are good price, ok quality, but the return window is too low on the envelope, top line of return address was covered. Using company program that would not let me adjust the placement of address. Returned them.

ENVELOPE TO SMALL - NEED #10

I am not bashing the envelopes I have used them for 2-3 years now- Just wanted to get to your attention, that this last box peal and seal-- doesn't stick I have to tape each envelope before goes to mailbox next box will open up and use one to check the stick-ability.

Windows in the wrong place & entire envelope is too short. Multiple folds needed multiple times and RE-folded bc they don’t line up. Strange folds at that. Epic fail. $33.00 THROWN AWAY in this economy. So sad. I should be able to return but not sure bc some were used.

We purchase about 40 boxes a month and have been very happy so far. This last lot has some major issues. Many of the envelopes are glued together and rip when you try and open them and the other ones do not fit the letter properly. When you close the envelope it does not line up right and the glue strip closes at an angle making it very difficult to seal it properly. Very disappointed with this shipment
