I like security envelopes because if I see a non-security envelope I can't help but to try to look closely at it to see the correspondence. I know this is wrong. Sometimes you can even see the color of a check or the outline of a logo. Not good. But since I've found these envelopes I don't have to worry about prying eyes like mine - well I've never really seen anything confidential or even noteworthy - but who want's to take that risk with someone else who may be more nefarious than I? Not me. And probably not you. So buy these. You'll enjoy the security.
I walked in the door and was greeted by a staff member. A quick explanation of my needs and I was whisked off to the location of same. 400 words are not needed if all was correct. I spent less time in the stored than answering this review...
These envelopes are costly if you're just going to use a few at a time but when you are facing a mailing of 100 or 1000 they are great. What a time saver!
