Style Description

When sending letters, invoices or statements, save the time and expense of separately addressing envelopes. Simply position the address to show through the window, or choose our full-face windows, which are large enough to show off the entire contents. Available in a variety of styles and colors, printed or plain.

Color Description

Same bright look as our other Bright Whites, with a little more heft than standard 24 lb., for an added sense of quality, and strength.

  • By Judy (Industry: Secretaryq) on Nov 20, 2013 Verified Buyer
We really like this envelope -- we configured our reports so that the address shows through the window and we don't have to type mailing labels now! Met Expectations? Met Expectation Usage? We use this envelope for mailing our reports to clients. Recommended: Yes, I would recommend this product.
  • By Envelope was fine for this job (Industry: Printer) on Sep 12, 2013 Verified Buyer
Good envelopes. However, had to have these offset printed because the window material did not hold up to our laser printing process. Bummer. Could use a "digital certified" i.e., heat-resistant version of this envelope in the future. I'm sure we will get reorders. Met Expectations? Met Expectation Usage? Client - Accounting Recommended: Yes, I would recommend this product.

  • By Perfect (Industry: Education) on Jul 23, 2013 Verified Buyer

  • By Hatch (Industry: Education) on Jul 5, 2013 Verified Buyer
The envelopes came at the expected measurements. The delivery was quick. Some of the envelopes did not withstand the amount of sheets we needed to put in each envelope. The seams split. There were about 6 sheets in each envelope. Met Expectations? Met Expectation Usage? Orientation Packets for New Students Recommended: Yes, I would recommend this product.

  • By Rich (Industry: Government) on Jun 26, 2013 Verified Buyer

  • By Has saved us time mailing! (Industry: Direct Mail Advertising) on May 27, 2013 Verified Buyer
I have looked forever, and no one carried 9 x 12 window envelopes that would work for our invoices we send our customers every month. We always had to use paste down "bill to" stickers which took forever to do. Now the send to address shows through the window on the envelope and has saved us tons of time sending our publication and QuickBooks invoices every month. The peel away self enclose is better than Staples envelopes and Staples did not even carry large window envelopes with a window in them. Other places I checked out wanted to charge 5 times as much as envelopes.com. Even Quickbooks did not have 9 x12 window envelopes. We will be ordering more. I highly recommend envelopes.com Met Expectations? Exceeds Expectation Usage? Recommended: Yes, I would recommend this product.

  • By Sara (Industry: HR Professional) on Mar 5, 2013 Verified Buyer
9x12 envelopes with a window were really tough to find to my surprise in my go to places. I became a customer of Envelopes.com because they were one of the only suppliers that had it. The product was exactly as expected, the way it looks and is described. Also the service has been great. I order a sample and then a bulk order and they came very quickly. Met Expectations? Met Expectation Usage? Mailing Recommended: No, I would not recommend this product.

The envelopes themselves were high quality as I expected.

    Printing Options Explained

    One Color Printing:
    One color printing means that your design contains only one ink color. Gray scale designs, contain a range of grays, and is also considered one color printing

    Two-Color Printing:
    Two color printing means that your design contains two different ink colors.

    Full-Color Printing:
    All print designs with more than two colors require an ink process called full color printing, which is also known as CMYK. CMYK stands for Cyan, Magenta, Yellow and Key (key means black). These four ink colors can be combined to print an unlimited number of colors. Remember, if your design contains more than two colors, select full color.

    White Ink Printing:
    White ink is a special, unique ink that prints best on darker colored papers and stocks. White ink can be printed with CMYK printing if the design contains white and additional color elements.
