Double Window Envelopes | Business Check Envelopes

These double window envelopes are perfect for mailing checks, invoices or other business documents. With two left-hand windows, this envelope will display both the return and mailing address for your item. These check envelopes also include a blue security tint lining, to help hide sensitive information.

We offer multiple types of double window envelopes, including Quickbooks check envelopes (sized 3 5/8 x 8 3/4) and standard double window envelopes (sized 4 1/8 x 9 1/2).

The Quickbooks envelopes are offered both with and without a self-sealing option in a 24# white paper stock. The self-seal option eliminates potentially messy glue, allowing you to close the envelope with a simple peel off strip. If you're sending out a high quantity of envelopes, you may find the traditional gum-flap quicker, as it can be moistened and sealed with less time.
