#9 Business Envelopes with Security Tint and Secure Seal

A standard security envelope that’s ideal for everyday business use, our #9 mailer is made from durable 24lb white wove paper and keeps your documents safe and secure with a strong glue seal and dark security tint lining. This envelope is equipped with a low profile flap design, making it easy to fold and stuff up to 10 sheets of standard letter size paper inside with room for a #8 return envelope so your clients can quickly return payments. It can also be used as a return envelope itself when sent inside a #10 envelope, making the #9 one of our most versatile envelope choices, simple enough for everyday letters and statements, yet professional and secure enough for high-profile business communications.

These envelopes are exactly what I was needing as far as size/windows and having self adhesive strip. Gave it 4 stars because the adhesive remains on the removable strip and will leave sticky residue on whatever surface you leave them on. So, make sure you throw the strip in trash with a liner immediately after removal. Adhesion is good and quality of envelope overall is good.

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.
