Very Useful Envelopes
I purchased these envelopes to mail a 13-page document to members of an homeowners' association. The size was sufficient to hold the document it was easy to stuff the envelopes the address labels and stamps stuck well to the outside of the envelopes and they sealed very nicely. It was a good purchase.

WORSE ENVELOPES I HAVE EVER PURCHASED
I purchased four boxes of these envelopes for a mass mailing at work. It took four (4) staff members over half a day to close all the envelopes with tape. Not the best issue to have when you are on a time crunch to get out 1113 letters. Very disappointing

No Sticky
The envelopes will not seal. Pull the strip off press together and they don't hold. Have to use tape to secure close.

Thinner and Cheaper Material
Ordered and product came envelopes are made of a cheaper + thinner material. I compared it directly to an existing stock I still had from previous order.

The sticky portion of the self-seal wasn't very sticky. I had to tape many of the envelopes

Terrible Seal
Staples has recently changed the quality of the closure on these envelopes because I've never had any issues with the self-seal closure in the past. I had a large mailing to get out and ended up spending over an hour taping the faulty closure of 400 + envelopes. Very disappointed! Don't buy if you plan on mailing anything out securely!

Not like they used to be.
These aren't as thick as the old ones were. Not sure if the envelopes would fall apart during transportation even after using tape. I will not purchase these again in the future.

No longer seal
These envelopes used to be great. However the past few times I've purchased them the envelopes will not seal. The "stickiness" when you peel off the strip to close the envelope is basically just for show now.

Terrible Quality
This item's quality has decreased every time I've ordered it. Initially it was fine but last time the sticky part was lacking and barely held onto the envelope. I had to secure it with tape for half of the envelopes. This time when I reordered there wasn't any sticky part at all or barely any. Very disappointing. The only redeeming feature was the price point.

Great Envelopes
Great quality envelopes with an adhesive that actually sticks without having to add additional tape or glue.

Best Ever!
I love this product! Our company has used other brands and I always had to tape it after sealing. This envelope seals well so no extra tape!

Staples Kraft EasyClose Catalog Envelopes 9" x 12" Brown 250/box
I order these envelopes because of the self close feature although the adhesive is not effective enough for me to feel assured that the envelope will go through the mail and stay closed therefore I tape each and every one of them before placing in the mail. In the long run my company is probably not saving money purchasing this item.
