#11 Regular Envelope - 24# White Wove (4 1/2 x 10 3/8) - Commercial Envelope Series (Pkg of 100)

These are a good quality white business envelope that are slightly larger than the standard #10 size most everyone is familiar with. The weight and thickness of the paper is standard to what you normally find on ordinary #10 or #6 white envelopes - they are not flimsy, though of course on the other hand they are not extra thick paper. These white ones are well put together so they will be secure going through the mails. They have the kind of glue on their flaps that you need to either lick or moisten - they are not the self sealing kind. If you want the extra heavy and thick paper #11 envelopes you should buy the brownish manila paper ones rather than these white paper ones. The main advantage of having some of these #11 size envelopes around is that you can enclose a regular sized self addressed stamped business envelope inside so that the person who receives it will be able to send a reply to you without having to look for an envelope or pay for a stamp or get you address wrong. They are also good for sending things that are just a tad bigger than a standard #10 envelope would easily hold. And there is no extra postage cost for using a #11 envelope over a #10 envelope.I would have given a 5 star rating but mine arrived with the plastic wrap broken open and with the envelopes having a bit of a curl to them from having been stored by the seller in a non-flat place. I put these under a heavy book and in a few days they were all nice and flat.

It is what they say it is. They come in plastic wrap, so they are not protected as well as one's in a box. Also, they are not security envelopes so you can pretty much see what's inside of them.But they can still work for certain purposes. I used them to stuff a #10 envelope inside that I put postage on so the recipient didn't have to use their own stamp. Also, if for some reason you wanted the security measure you could add an additional paper to the outside of what ever you are mailing.Or you could just get some #11 security envelopes.

I needed some slightly larger envelopes so I could put an envelope inside another envelope for business reasons. This size is just what I wanted. I looked for the size at several big-box office stores, it simply wasn't available anywhere. I'm also pleased that these envelopes are white, and not manila.

From time to time I have to send someone's entire #10 envelope back, and this #11 size allows me to do that without having to fold the #10. I'm sharing them at work, and my coworkers think it's a good idea.

Just needed a small quantity of over size envelopes. They are just what I needed.

i purchased this so i can ship like a return envelope with my letters so , i put #10 envelopes inside the #11 because two #10's wouldn't fit inside each other ...anyways this is a great envelope but its not security proof so that kind of sucks...but still a great envelope.

If you need to nest envelopes and don't want to fold them, having #11 envelopes around is very helpful. These were a good price, for this unusual size, and seemed to be good quality.

I needed a larger envelope to fit a regular business size envelope in - these are the perfect size and arrived in perfect condition. Thank you!
