Window design

Double window envelopes are a great way to streamline your business's mail out process. These high quality envelopes features two transparent windows, allowing you to easily display addresses without needing to affix separate address labels. Ideal for use with accounting statements and invoices, double window envelopes make it easier than ever to send out mail in bulk. Double window envelopes have two rectangular cut-outs on the front of the envelope that reveal both recipient's name and address as well as the sender's contact information. This makes it easy to identify who the letter is intended for, saving time and effort when sending out multiple pieces of mail. The windows also help reduce paper waste by eliminating the need for separate address labels.

Secure closure

Each envelope comes with a secure gummed flap that will keep contents safe and secure during transit. Double window envelopes come in several sizes so you can find just the right envelope for your needs. Double window envelopes are made from durable material that won't rip or tear even during long distance shipping. The paper is thick enough to prevent confidential documents from being viewed through the windows and offers excellent protection against moisture damage as well as dust and dirt buildup. Staples has a wide selection of double window envelopes available in different sizes and materials, so you can find exactly what you need for your business mailing needs. Choose plain white envelopes or opt for colored options like blue, green, yellow - either way, you're sure to get high quality results every time!
