  • By Alexa Louser (Industry: Realtor) on Jan 13, 2017 Verified Buyer
The envelopes exceeded my expectations! LOVE the Mandarin orange color; great match to our NextHome franchise color. The sealant is super strong. These envelopes stand out in the mail and get noticed! Met Expectations? Exceeds Expectation - Peel and stick is super sticky and can't be opened and resealed without damaging the envelope. Weight of the envelope is good and they are sturdy. Fantastic color assortment. Usage? Mailing Reports/advertising Recommended: Yes, I would recommend this product.

  • By Lochlin Broatch (Industry: Other) on Jul 22, 2015 Verified Buyer
Purchase and checkout was easy. In house Customer support was fantastic and helped me pick the right color to match our company logo. Delivery ti Canada was or I should say is terrible. Absolutely terrible. Unsure how much ships to Canada but expect a long and brutal delivery cycle. I was told I'd receive my package in 6 days. It's now been 2 weeks and have not yet seen the envelopes. We were forced to do our mail campaign without them. Strongly advise get a different carrier for Canadian delivery (hint: I'm in Winnipeg, UPS carried my envelopes to Richmond B.C., halfway across the country in the wrong direction, and then let them sit their for five days before shipping them again. That's brutal. Absolutely brutal.) Otherwise you guys seem to have this figured out but your Canadian shipping is god awful. Met Expectations? Below Expectation - Delivery took more than twice as long as expected and rendered my purchase useless. Usage? Direct Mail Campaign Recommended: Yes, I would recommend this product.
  • By Sue (Industry: Purchasing/Operations) on Oct 8, 2014 Verified Buyer
These look great and the black printing is bold. Met Expectations? Exceeds Expectation - Very polite people helped me! Usage? Mailers Recommended: Yes, I would recommend this product.

  • By Sue Kelley (Industry: Education) on Dec 23, 2013 Verified Buyer
I love these envelopes! They look great and the ink applies well. The sticky adhesive is strong as well and won't come open in shipping. Met Expectations? Exceeds Expectation - Ink was great & shipping fast. Usage? Mailers for our paperwork Recommended: Yes, I would recommend this product.
  • By Susan (Industry: Education) on Jun 5, 2013 Verified Buyer
Love the orange color; it matches one of our school colors. I think they will really get people's attention beyond the usual mail and advertisements. Met Expectations? Met Expectation Usage? We use these orange envelopes to send information to prospective students. Recommended: Yes, I would recommend this product.

  • By Diane (Industry: Event Planner) on May 9, 2013 Verified Buyer
I used these bright orange envelopes for an intercompany mailing. I wanted to make sure everyone noticed them. They did the trick. I love the peel and stick closure! Met Expectations?

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.
