Top Flight Number 10 Boxed Security Envelopes, Strip and Seal Closure, 4 1/8 x 9 1/2 Inches, White, 45 Envelopes per Box (6900120)

I do like the strip and seal envelopes the best. They make the envelope very secure.

Hi have using these security envelopes for years. They’re self sealing, quality, and at an affordable price. Highly recommend them

I'm not sure it's possible to "love" envelopes, but I gave them 5 stars because they do what they're supposed to, they are good quality, and the price was decent. I'm not sure what else you could ask for in an envelope.

Very satisfied with these envelopes. Easy to peal the strip off and they stick well. I would buy again.

What are you looking for in a security envelope? Security, right? This one is a nice medium weight, with the typical blue cross-hatch surface inside. It also has a pleasant satiny feel. And best of all, it seals by removing a thin paper strip across the inside of the flap, which really sticks the first time you press it down. It appears to be the same type of sticky product that the post office now uses on stamps. That is, with some diligence you can un-peel it and then stick it back again. In an envelope that is a handy feature for those of us who occasionally forget to enclose something that was meant to go inside. It also means that someone else could open the envelope and re-seal it, which could compromise the security. For me, the convenience trumps the remote chance of tampering. And un-peeling the flap would leave marks showing that it had been tampered with, so that is another protection...but I wanted you to be aware of that possibility. All in all, I will order this product again. Good value, good quality.

Hey, they're envelops.. What else can I say?

Affordable and secures easily without the need for extra moisture.

Exactly as described
