Easy-Fold Mailers 12.5 x 12.5 x 2 in

These white Easy-Fold Mailers measure 12.5 by 12.5 by 2 inches and come in a pack of 50. They are designed for businesses and individuals who ship flat or moderately thick items such as documents, books, or boxed products. The self-folding construction removes the need for separate boxes and tape, speeding up the packing process for high-volume shippers.

Replaces rigid boxes and bubble mailers

Switching from rigid corrugated boxes or padded bubble mailers is worthwhile when you need to reduce storage space and packing time for items that fit the 12.5-inch square footprint. The flat-stored mailers expand to a 2-inch depth, offering more structure than a standard poly mailer while occupying far less warehouse room than assembled cartons. This jump makes sense for operations shipping consistent, medium-sized goods where speed and storage efficiency matter.

Check item dimensions and weight limits

Before ordering, verify that your products fit within the 12.5 x 12.5 x 2 inch internal space and do not exceed the mailer's structural capacity for safe transit. Confirm that your shipping workflow can accommodate the fold-and-seal method without additional reinforcement materials. Ensure the white exterior meets any branding or labelling requirements for your outbound parcels.
