• Perfectly fits QuickBooks Checks, or other computer printed checks: checks will slide in easier with a slightly wider design than the standard 2 window 8 5/8 envelope
  • Checks amounts and memos will not be visible: Only addresses will show through our unique double window design with no need to change QuickBooks, QB Online, or Quicken settings
  • Provides complete check security: your laser checks will be hidden with our security tint design
  • Just moisten or lick the flap and fold it over to create a strong lasting seal: Save money with our strong gummed seal design is quick and easy and is guaranteed to stay sealed (NOT SELF SEAL)
  • Maintains professional look and feel throughout transit with our durable 24 LB white wove envelope paper

You can't really guard against a bad guy from stealing a piece of mail and opening it. However, this envelope provides security from people being able to read what's on the check, thanks to the pattern printed on the inside. Further, the seal keeps the envelope closed in transit. I use Quicken checks and the envelope windows allow plenty of space for the return address and mailing address to show through. Even though I don't use a lot of these envelopes, the 500-pack was just a little more cost than a 100-pack. Can't pass up a bargain! When a vendor does all that is expected, I award five stars. This vendor and product earned that rating.

As my title says, these envelopes are excellent quality at a good price. I didn't even notice that I had changed from the more expensive ones the check companies sell. I definitely will order these again! (This is in stark contrast to the generic name/address labels I ordered from another company instead of the expensive Avery ones. The generic name/address labels were inexpensive, but poor quality and thus a total waste of money.)

The envelopes look good, seal well. and are a good value. One end of the box had broken loose from the tape and exposed some envelopes. Thankfully it didn’t rain so all was well.

Blue Summit Supplies are Awesome! I really don't have time to write reviews - but I love their products. They cost slightly less than their competitors - but I think their quality is slightly better. These are definitely "privacy" envelopes; and they seal securely. I use them for Intuit QuickBooks accounts payable vendor checks. We use the full sheet laser checks; keep the bottom stub for our records - mail the check and the middle stub (which has transaction detail) to the vendor. The QB check fits perfectly into these envelopes - with our name/address showing in the top window; the vendor name/address showing in the bottom window. Before, we bought from a "deluxe" supplier - and the price was almost 3x's as much (and sometimes their envelope window cut off the bottom line - which is a problem because it has the zip code... and sometimes it seemed their envelopes were getting a little "tight" to put my checks into). No problems with Blue Summit!

This is our second order of checks. Envelops come with all envelopes ready to be stuffed. (No envelopes accidentally sealed due to improper packaging or exposed to environment that makes some do this). I am very pleased, I use approximately 450 envelopes per month.

These work perfectly on our checks that were designed for QuickBooks. They are better than the check window envelopes we have bought in the past from Staples and OfficeMax in three ways: 1) The company return address window does not cut off the top of the company name 2) the addressee / mail-to window blocks the memo line at the bottom of the check enough to make it unreadable 3) we never go through 500 checks fast enough to keep those peel-and-stick envelopes from drying out. I'm not sure how long they are supposed to last, but we inevitably end up sealing them with glue sticks over the dried peel-and-stick. So these do require moistening, but they will last longer, and seal more neatly.

These are well made and packaged perfectly for storage. Not much else you can say about an envelope - happy with the purchase.

Sealed with a quick wipe of water sponge. Off into the mail. Received one back for incorrect address & the envelop held up beyond expectations. Thank You!

These envelopes are perfect for my needs. The windows are just right to show the address and return address from my checks printed on Quicken. And they are thick enough that you cannot see throught the envelope to see the other information written on the check. It's a big box and will take me a long time to go through these.

THIS ENVELOPE FITS TIGHTLY TO THE CHECKS WE FOUND WOULD FIT IN THEM WITH BOTH WINDOWS SHOWING THE APPROPRIATE INFO IN EACH.
