These envelopes take care of my 2 biggest concerns. I HATE licking envelopes to seal them! These are self-sealing which I LOVE. Also I mail out a lot of checks and I'm uncomfortable with envelopes that I can see through. These are non-see-through!
Paper the envelope is made of seems thin and easy to see through. I meant to get the security envelopes that you can't see through. Product is not go if you want to hide the contents. I wish I had realized that I didn't pick u[ security envelops.
I just used a box of 100 envelopes for a mass mailing from my school. They were great -- easy to peel the strip easy to seal secure good heavy quality paper.
