Save Time and Money with The GSM Office #10 Self Seal Double Window Envelopes

It can be a pain to send invoices, statements or legal documents through the mail with normal envelopes. You must either use a standard envelope and spend time addressing the envelope, or struggle with getting the correct address details to line up to show through the envelope windows. Our envelopes are specifically designed to fit most standard printed invoice, statement and legal document layouts, allowing the sender and receiver addresses to be seen while hiding the contents.

High Quality Construction

Our self seal double window envelopes are made to high quality standards with the following specifications:

#10 Envelopes with 4 1/8 inch width and 9 1/2 inch length.

Double window design to accomodate most printed invoice, statement and document layouts (see the product pictures for exact design specifications).

Made with 26 lb white paper and a blue woven security pattern.

Uses a strong adhesive peal and self seal that does not require moisture to seal.

Comes in a convenient box of 500.

Money Back Guarantee

These self seal double window envelopes come with our money back guarantee. If the envelopes fail to live up to your expectations, simply return them for a full refund.
