Staples Double‑Window Laser Check Business Envelopes, White, Security‑Tinted Gummed Closure, 8.875" x 3.625", 1000/Pack

Send important documents securely with these envelopes. Moderate dimensions make them a viable option for shipping folded documents and checks, while the interior security tinting ensures that sensitive documents are safe from prying eyes. Made of 24 pound woven paper, these envelopes are durable enough for regular use but light enough to help you save on shipping costs.

Double-Windowed
The two windows on these check-size envelopes let you avoid printing extra shipping labels. Simply print the client's name, address and your return address directly on the document. The standard window placement means that many programs come with compatible templates, allowing you to use the windows to cut back on preparation time and avoid the expense of external shipping labels.

Security and Durability
These security-tint envelopes come with a printed design on the interior that prevents people from seeing through the envelope, ensuring that your shipped documents are safe while in transit. In addition, the moderate weight of the paper provides extra protection while your mail is in transit.

Straightforward and Practical
These Staples envelopes conform to standard envelope dimensions, which makes it easy to find compatible items. The gummed flap is easy to close, and the square shape makes both opening and closing the flap simple.
