100% Secure Payments
Conformer envelopes expand uniformly to fit whatever you slide inside. Shipping documents, booklets, or even books is easier than ever. These mailers measure 9.75” x 12.25” and were designed with flexibility and versatility in mind, since they fit all manner of mailings and store flat for easy, space-saving storage.
Patented construction incorporates 14 pt paperboard, inset glue seams, and uniquely engineered expanding corners to provide extra durable strength. Our mailers expand along pre-scored lines to fit an extra 5/8” worth of thickness – but only when you need it. This eliminates the need for fillings like bubble wrap or packing peanuts. And the contents within your mailers will stay flat, secure, and safe throughout transit thanks to the heavy-duty peel-and-seal flap which provides a permanent seal without the need for extra packing tape.
