  • By Michael ODonnell (Industry: Other) on Oct 23, 2018 Verified Buyer
Good quality product. Met Expectations? Met Expectation Usage? style Recommended: Yes, I would recommend this product.
  • By Lake Ridge (Industry: Non-Profit) on Jul 24, 2017 Verified Buyer
We love these envelopes! They are so professional looking and the ready to seal strip makes bulk mailing a breeze. I would recommend these envelopes highly! Met Expectations? Met Expectation Usage? Professional Mailings Recommended: Yes, I would recommend this product.

  • By Mary (Industry: Other) on Oct 26, 2015
The slate colored envelopes with square self-adhesive flap were everything I was hoping for and more. Need a gray envelope to coordinate with a black and white letterhead for a campaign mailing. The white mailing label with black script writing really pops . As one person stated, you want to open this envelope. Envelopes look so professional. Even my print shop guy who coordinated the campaign letterhead commented on excellent quality. Arrived on time. Boxed well. Very pleased and will definitely order from this site again. Met Expectations? Met Expectation Usage? Campaign mailing Recommended: Yes, I would recommend this product.
  • By Steph (Industry: Student) on Jul 2, 2013 Verified Buyer
I'm a big fan of nice stationary and the average white envelopes from the stores do not suit my creative need. The color and thickness of paper is perfect and the sticky seal actually works. Not to mention that these envelopes are eco friendly and recycled :) Definitely purchasing them again. Met Expectations? Exceeds Expectation Usage? Everyday Mailing. Recommended: Yes, I would recommend this product.

  • By Danielle (Industry: Bride) on May 9, 2013 Verified Buyer
These envelopes exceeded my expectations. They were a little darker than I expected, but the quality was excellent. I didn't know they were self-adhesive when I ordered them, and was happily surprised that they were super sticky so there was no chance of them coming open in the mail. Even the recycled paper was very good quality! Met Expectations? Exceeds Expectation Usage? Wedding invitations Recommended: Yes, I would recommend this product.
  • By Amber (Industry: Bride) on Feb 3, 2013 Verified Buyer
Beautiful color! Good quality paper & Construction. Perfect for our invites! Met Expectations? Met Expectation Usage? Wedding invites Recommended: Yes, I would recommend this product.

  • By MBO (Industry: Interior Designer) on Jan 29, 2013 Verified Buyer
Love the envelopes but felt "free shipping" was not accurate when it really meant you could pick-up for free (where couldn't you?). I live on the other coast so I will buy local next time. Met Expectations? Met Expectation Usage? business stationary Recommended: Yes, I would recommend this product.
  • By Perng (Industry: Medical Services) on Dec 10, 2012 Verified Buyer
Great paper , looks good Met Expectations? Exceeds Expectation Usage? Gift certificates Envelopes Recommended: Yes, I would recommend this product.

  • By Kristen (Industry: Bride) on Jun 25, 2012 Verified Buyer

  • By GABBI (Industry: Stationery Designer) on Apr 25, 2012 Verified Buyer
My color scheme was yellow & grey, and the invitations worked out beautifully! I couldn't ask for a better envelope to match my design. The envelope is exactly as described. Met Expectations? Exceeds Expectation - perfect! Usage? Anniversary Invitations Recommended: Yes, I would recommend this product.

    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.
