the only one the boss likes!
super expensive compared to other envelopes, but the only on the boss likes. I feel though that one can easily reopen and close again.

something has changed
I have ordered these before and they were fine. I am a Quickbooks user and this batch the window no longer lines up to show my addresses that are printed on my checks. I have to fold the checks under to make sure they show out the window. They also do not seem to seal as well. They come back open if I don't seal them multiple times and put them under a lot of pressure...

Window placement has moved. Won't work for checks.
I have been ordering these for years. We use them for our printed checks. The last box I ordered has a new layout. Along with the "no moisture needed" text on the back, the window is much lower and narrower than it used to be.
In my picture the top envelope shows the "old" format, and the bottom envelope shows the current format. It won't work for us. Returning and lo...

Self seal
Self seal won't adhere. It's a must on a self seal envelope.

Self Seal does not stick
The self-sealing flap does not stick/seal .
I end up having to tape shut every single time. I would have returned but I needed to use them straight away so I am stuck. Buy something else.

Self seal does not stick
These are worthless - the seal dose not stick and we need to use tape to close them. I am surprised Staples sells such poor quality products as this.

It took about 11 weeks to arrive (envelopes are probably fine--I haven't used any yet)
The envelopes are great, I hope (I haven't used any yet because we're still going through our small box we had to buy to hold us over while we waited). I ordered these envelopes on May 26, 2024 and they arrived August 9, 2024. That's about 11 weeks, which seems a little extreme....?

Disappointed
Despite saying you could use a printer on this, the envelope "melts" and crinkles. Does NOT work on a laser printer -- at all.

Great envelopes!
I needed more envelopes to send church statement of giving, and didn’t want to lick or wet any more. They work great! And they arrived quick too.

low quality item
Envelope is low quality. Paper is very flimsy and seems to be cut unevenly. The glue does not stick well. Do not waste your money.

Adhesive problem
Approximately 10% of the envelopes in the box do not have adhesive applied correctly - not in the correct position and also an insufficient amount of adhesive.
