Staples 9 x 12 Self‑Seal Catalog Envelopes, Brown Kraft, Strong Secure Seal, Heavyweight Mailing Envelopes, 100/Box

Mail documents safely and securely with these Staples envelopes. Sturdy construction out of kraft paper means you don't have to worry about damage in transit, and they remain a convenient option, thanks to the self-sealing flap system.

Durable and Stylish
Constructed from 28-pound kraft paper, these catalog envelopes can withstand rough handling and various transit conditions, making them perfect for mailing items that need to be left unfolded. The thickness not only ensures that your documents arrive in good condition but also increases privacy by preventing anyone from seeing inside the envelope. The light brown color gives your mail the classic look of business correspondence.

Convenient Self-Sealing
The dual-adhesive surface on these catalog envelopes lets you seal them shut simply by pressing the flap down. No moisture is needed, but these self-sealing envelopes still close as tightly and tidily as any other. This convenient feature save time and saves you from having to use messy sponges or tape to seal the envelope.

Available in Bulk
With 100 envelopes to a pack, it's easy to stock up your supply closet. If you only send large amounts of mail occasionally, the pack is not so big that you're left with hundreds of excess envelopes once everything is sent. Whatever your needs, it's easy to ensure you always have enough envelopes on hand with this pack.
