The best envelope on the market....
The only one I use for business - it's heavy weight and no one can see thru it.

Self seal envelopes
I don't like them. They are hard to use and actually put items inside because the side flaps are so short. It is really hard to get paperwork inside.

Self-Sealing Security-Tint #10 Envelopes
There is no skicky stuff on the envelopes. When you feel off the tab, you have plain paper.

Great for mailings
I volunteer at several local non-profits. For mailings from 20 - 200 these envelopes speed up the process of stuffing and sealing. Once sealed it stays sealed. I can buy cheaper envelopes but efficiency and speed is lost. These are worth the extra cost.

Not completely self sealing
In my box all 500 envelopes are only self sealing about 60% of the way. The gummy stuff is missing on left side of envelope. Have to apply envelope adhesive to the left side.

Don't seal
We got these to save time for a large mailing. Mistake. One, because of how the envelope is folded, it is difficult to quickly open and stuff. Two, about every fifth envelope simply didn't seal like the sticky parts were too old. Find another solution for your large mailings - this was not a time saver at all.

DOES NOT HOLD THE SEAL
IT IS A GREAT PRICE BUT IT DOESN'T HOLD THE SEAL. I USE TAPE TO KEEP IT CLOSED. If you don't mind going the extra mile, its worth it.

self stick envelopes
These are better than the other self-stick envelopes we had bought. The envelope seals much better and quicker
