Save Time and Money with The GSM Office #8 Self Seal Double Window Envelopes

It can be a pain to send printed Quickbook checks 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 check details to line up to show through the envelope windows. Our envelopes are specifically designed to fit quickbooks and other standard printed 3 1/2 inch by 8 1/2 inch checks, allowing the sender and receiver addresses to be seen while hiding the check amount and memo line.

High Quality Construction

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

#8 Envelopes with 3 5/8 inch width and 8 11/16 inch length.

Offset double window design (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.

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.
