9.5×12″ Poly Shipping Mailer

Made from water-resistant white poly, this mailer measures 9-1/2″ wide by 12″ tall with a 2-inch lip, giving you a secure closure using the peel-and-seal strip without extra tape. The lightweight design makes it easy to stack and store flat, while the white poly material helps keep contents dry in damp or wet conditions and resists light tears and punctures. Suitable for shipping documents, photos, prints, and other flat items, it provides a practical layer of protection during transit. The simple, smooth surface accepts labels and handwriting. A straightforward option for office, e-commerce, and personal mailing where moisture resistance and easy handling help.
