Mailing Boxes

Safely mail your products in Confirmailer® mailing boxes from The Supplies Shops. These lightweight mailing boxes are made strong with N-flute corrugated cardboard. Per-box sizes range from 4.375 in. x 11.5 in. (.375-in. width) and 4.125 in. by 8.625 in. (.75-in. width) to 5.125 in. x 10 in. (.8125-in. width).

Confirmailer® brand sturdy mailing boxes are popular for use as e-commerce mailing boxes. That’s because they are lightweight, which can lower shipping costs by weight, and these mailer boxes have easy peel-and-seal openings for added security.

Confirmailer® brand mailing boxes and Confirmailer® mailers are made by the Calumet Carton Co., and are designed with smooth exterior surfaces for easier use of our inexpensive address labels for mailing boxes.
