Peel and seal flap is quick and easy to use without any need to lick or moisten the glue
Dark security tint lining keeps your important documents securely concealed throughout transit
Frustrated by flip-and-seal envelopes sticking to other mail, or the yucky taste that comes with standard gummed seal envelopes? A peal-and-seal design is the answer, with no mess, no residual stickiness, and no need for moistening. A standard security envelope that’s ideal for everyday business use, our #9 mailer keeps your documents safe and secure behind the strong glue seal throughout transit and a dark security tint lining.
Made from a durable 24lb white wove paper, this envelope comes equipped with a low profile flap design, which makes it easy to fold and stuff up to 10 sheets of standard letter size paper inside with room for a #8 return envelope as well – so you can make it simpler than ever for your clients to quickly return payments to you.
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 that’s simple enough for everyday letters and statements, yet professional and secure enough for even high-profile business communications.

This envelope is equipped with a self seal, which means it requires that you peel away the protective strip to reveal the glue. It does not require moistening, but cannot be used in a bulk mail machine. For envelopes that can be used in a mail machine, you’ll want to use a gummed seal envelope.
This envelope is not suitable for printing in a laser printer, as the heat will melt or warp the windows.
While this envelope will work with QuickBooks invoices, it is NOT suitable for sending QuickBooks checks, as check information will not line up properly in the windows. Please click herefor envelopes suited for mailing QuickBooks checks.

These have worked well for me in the past of Quickbooks invoices. I am waiting for my order as the delivery service is having problems delivering them to the correct location. Huge problem with delivery, nothing wrong with the product!
Hi, I find myself putting pieces of scotch tape at each end because the self stick doesn't go all the way to the end and leaves loose flaps. I have also noticed (definitely not all your products) that when I receive mail in similar envelopes that the ends are also frequently taped down.
Other than that - Blue Summit is the best!
