#9 Double Window Security Envelopes, Flip and Seal, 500 Count
Durable and professional #9 business envelope for mailing invoices, statements, and other office mailing needs
Roomy enough for a return envelope to be included, so you can get paid faster
Low profile flap design creates a wide opening for easy and quick envelope stuffing
Flip and seal flap is quick and easy to use without any need to lick or moisten the glue
Perforated top edge makes it quick and easy to open without the use of a letter opener or messy tearing
Dark security tint lining keeps your important documents securely concealed throughout transit
In offices that send a high volume of business mail, making the process as quick and streamlined as possible is key. Eliminate the hassle of having to moisten standard gummed seals or removing the protective strips used in peel and seal envelopes; you need to go for the easiest closure of all, which you’ll find in flip and seal envelopes. No licking, peeling, or taping required; simply flip up the folded edge, then flip down the flap!
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 can easily hold up to 10 sheets of standard letter size paper inside and features a perforated top edge to make it easy for recipients to open their statements. 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.

#9 double window envelope
Dimensions: 8 7/8 inches X 3 7/8 inches
24lb white wove paper
Package quantity: 500 Count
This envelope is equipped with a flip and seal closure, 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 should be stored in a dry, clean environment, as the latex glue on the flap will deteriorate when exposed to dust or moisture. The glue will also break down over time, so for best results, expect the self-sealing glue to bear a standard shelf life of about 12 months from purchase.
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 here for envelopes suited for mailing QuickBooks checks.
We’ve tried a lot of different envelopes. These are by far the best (and very reasonably priced) envelopes we have used. We will continue to buy from Blue Summit Supplies. They have great customer service and we have always been very happy with the products!
