Professional look and great time saver
This is a great product and at a very reasonable price. As a small membership-based nonprofit we send out an acknowledgement for every donation received. Having a quality #9 double window self seal security envelope has eliminated the need for hand addressing or generating mailing labels. Our logo and up to 4-line addressing fit the windows perfectly. The benefit of all the time saved and the professional look easily justifies the cost of the product.

LOVE THEM BETTER THAN QUICK BOOK ENVELOPES
MUCH BETTER THAN HARD TO FIT QUICK BOOK DOUBLE FOLD SEAL ONES. LOVE THEM. THE TOP WINDOW SHOWS THE PAY TO THE ORDER OF AND THE ADDRESS SHOWS THRU THE BOTTOM PART. LOOKS GOOD AND AGAIN MUCH EASIER TO PUT CHECKS IN THE ENVELOPE. ALSO 20 BUCKS CHEAPER THAN RIP OFF QUICK BOOK ENVELOPES.

Meet My Needs at Fair Price
The envelopes seem to be well made and they seal easily without appearing to come loose. The double windows line up correctly. The only reason I don't rate them five stars is because I have not used them for very long.
