Awful Product Redesign
I used to love these envelopes. I recently purchased the exact brand and product number to find they have been redesigned with a major quality downgrade. They are now cheaper, thinner, more flimsy, harder to stuff because the back side is shorter, and the self sealing strip barely works. I will never buy these again.
Top envelope is the old design, bottom is new. Even...

Perfect Envelopes
The Staples Envelopes #8 3.625 X 8.625 in White are perfect for all my business needs. They have a very clear viewing window for the mailing address and return address. They seal nicely and do not reopen due to the Instant Seal lift-tab (thankfully...no need to lick to stick). They are lined with security printing for privacy. They check all my boxes for a good busin...

Middle of the road envelopes
If there is anything I could ever put a three star rating on, these would be first. My overall impression of these envelopes is that they are useful for payroll or something similar, but they seem cheaply manufactured and even translucent to the point of being unable to use for private information. The size looks great, normal letter size and the window boxes are large ...

If it's not broken...
I reordered the envelopes that we have been using for years because they were the only self seal envelopes that worked with our checks. When I received the order, they are totally different. This redesigned version is terrible. The windows don't align properly, the adhesive is weak and also not lined up correctly and to be honest, it is a pain just to get a check into t...

Do NOT like these envelopes
I thought I was reordering the same thing I had before. The flap opening changed to a bigger opening and it is a pain to get the checks into them without catching on all the exposed edges. The gummed envelope does not match up so it is exposed when the flap is closed. I can only imagine other things are catching on my envelope in transit. They re-open too easily and...

OMG I hate these. It is hard to get the folded paper into envelope as only a small portion of the edges is exposed.

Horrible redesign
Everything I try to stick in the envelope gets stuck on the flaps. The glue is horrible.

Redesign is horrible
I don't know why they re-designed these. They weren't great before but now they're worse. The windows don't line up properly and the self-seal adhesive on the flap does not match up with the adhesive on the envelope so there is this little strip of exposed adhesive after they're sealed. I will probably order a different brand next time and hope they're better than these...

Horrible Envelopes!
Do not buy these envelopes unless you want to have to use a glue stick or tape to close them. The self adhesive feature (that in the past was wonderful and quick and easy to use) does not line up properly, so the envelope will not seal without adding glue or tape. So dissapointed!

Self Seal Security #8 Dbl Window Envelopes
The entire box seems to be defective the flap that folds over to seal doesn't line up with the adhesive. We have to tape each flap in order to seal the envelope and cover the adhesive.

# 8 double window self seal envelopes
They work well with the check system we use for invoicing; the address fits in the middle of the window.

Not Worth a Star!!
The new design is terrible! They don't deserve even 1 star! Used to really like these envelopes for Quickbook checks. Now they changed. The glue is half way exposed, glue strips don't match up to each other, takes twice as long to put the checks in the envelope, window spacing is incorrect. Will never buy these again.

Terrible envelope
We always order this item for our company checks.
The last time we received them they were such bad quality. Even the window size and spacing is different so that the address is hard to read. How can they change that and still give it the same item number.
The envelope is also so flimsy it takes twice as long to get the check in the envelope as before. I would not buy ...

Not terrible, but not great
The corner of the envelope is glued, so it takes extra effort and time to place something inside. I would not recommend purchasing, unless you're in a bind.
