#10 Left Window Envelopes Self Seal - 80/pack - 4 1/8 x 9 1/2 inch - Business Envelopes #10 with Flip & Seal Closure, Security Tinted Envelopes for Invoices & Statements - White Envelopes Letter Size

Great envelopes but I ordered the wrong size.

These are great! The self stick is excellent. They are very easy to use.

And by "work" I mean that they can be filled with folded paper, sealed, and mailed. I didn't expect them to do my laundry or make my bed, and they don't.

The #10 Single Window Security Self Seal Envelopes are everything for easing mailing. The envelope security print is well done - you cannot see what's inside when held up to the light - the window is the perfect size for the address and does not reveal anything else but that.The #10 Single Window Security Self Seal Envelopes self sealing feature is very unique in that you have to flip up and remove the tape to close, this adds extra security to what's enclosed. I will be purchasing more of The #10 Single Window Security Self Seal Envelopes in the future, THIS ENVELOPE IS IT!

I like these because for the rare times I need to mail something, I can just print both addresses on the letter, and not have to print the envelope itself. Then just fold the letter so it fits nicely in the envelope and mail.

Theyre envelopes. They do what they’re meant to do- mail items elsewhere. The only issue I have is where they say you can just stick the pieces of the back together without water or anything. They do stick but it’s pretty easy to unstick them. So maybe add licking them or tape or something like that and they’re fine after!

We all need security envelopes at times. I expected the self seal envelope to be like others I've used, with which you pull of a paper cover and stick the adhesive.This envelope has two adhesive seals that you match and stick. It works. It's simple to use. But, I'm disturbed that I can seal, reopen, reclose, let sit a minute, reopen and reseal again without damaging the envelope. I love that I can correct a mistake and reopen and add something I left out, but I'm concerned about who else can open and reseal before the adhesive becomes permanent.It does seem to become permanent after 5 to 10 minutes.The envelopes also don't come in a box, which I prefer for the organization of my desk space.

These are great too have especially during tax season. The self sealing aspect is really great. These are also safe for laser printers too. These are tinted for security and can be used for business invoices. I would buy these again, because I can always use more envelopes.
