Wrong envelopes in the box.
I ordered window envelopes and the box is marked accordingly however the envelopes in the box are not window envelopes. I'm going to try ordering again.

Window placement is wonky
We've purchased these envelopes several times but the quality has decreased to the point where we likely won't order them again. Where the address window is located is not standard- it varies up to a third of an inch in any direction across each of the 500 envelopes. This causes more than half of them to not properly display the address printed on checks and letters. T...

Not good for printer!
The envelopes themselves are fine but the plastic window melted when we tried to print our logo on the top left leaving it wrinkled and difficult to see through. The description said "the adhesive strip forms a tight strong hold" for sealing the envelope which is also not the case. Adhesive strip not strong. I returned the item.

cheaper quality
Staples envelopes have decreased in quality. I have purchased the same three envelope types for over a decade and they are now all flimsy with a thinner adhesive strip that does not reach the edge of the flap. I am looking for a new source for envelopes.

cheap quality envelopes
These envelopes are not good quality. They are made extremely thin. When I went to print our company logo & address in the top left corner the plastic window of the envelope "melted". If you are wanting a professional quality of business envelopes then do NOT purchase these.

Fits Our Mailing Needs
Basic No.10 envelope with security paper left-side window that works great with our preprinted checks for mailing. Easy to use adhesive seal.

Great envelopes
I use this type of window envelope for sending out statement reminders. I chose these because of the easy close strip which makes it faster to get them out. I also like the feel of them. Very smooth. I recommend them to anyone looking for size 10 single window envelopes.

Ok for price
I've had to throw away quite a few envelopes because they were glued shut on the inside. The seal strip sticks well enough.

They do not stick at all
The envelopes I received must’ve been defective. The adhesive is not strong enough to seal the envelope. I had to tape each one closed.
