Very low quality
These were the least expensive large envelopes available at Staples. Since I needed to have 30 envelopes to send information to every family in my classroom I was interested in saving some money. Unfortunately these envelopes were simply a bad choice. In short the adhesive strip is worthless. They don't stay sealed while stacked in a box waiting to be distributed....

Convenient envelop
These envelopes are strong and easy to use! The adhesive does stick but it not as secure as it should be for mailing!

Envelopes
We were overcharged $13 a box and they required glue sticks to stick.

1/2 the envelopes were glued shut
1/2 of the envelopes were unusable because of being glued shut. The gum seal wasn't strong enough - it was necessary to add another piece of tape to be sure it stayed closed. These were just not manufactured correctly.

These envelopes do not adhere. I needed to go over them with a glue stick.

Low Quality
They are not very sticky. The white paper you peel off rips in the middle and then it's hard to remove after that.

Envelopes were junk…
Bought these envelopes because they had a self sealing flap. The adhesive so so weak it couldn’t even hold the envelope flap closed. I had to tape every single one of them I’ve used so far.

Doesn't seal
Doesn't stay sealed and the envelope itself feels super thin. I need to use tape each time I use them.

Steep Quality Decline
Staples should be ashamed to call this an envelope...it's a brown piece of paper you have to turn into an envelope on your own. These used to be good envelopes. About a year ago I noticed the glue strips had been changed. They were okay but not as good as they had been. They have gotten worse and worse; at this point we have had to tape them together because the middl...

Perfect Envelopes
I am Librarian for 2 major choirs. I distribute their music in these brown envelopes. They are affordable easy to close and work perfectly year by year for me. I have been using these envelopes for the past 12 years.
