12 x 12 x 3" White Literature Mailers

These 12 x 12 x 3 inch white literature mailers are built from ECT-32-B corrugated board with an integrated tab-lock closure that secures without tape, staples, or additional supplies. The white exterior delivers a clean, professional finish that holds up through transit.

Designed for flat or low-profile products, these mailers suit e-commerce fulfillment, retail distribution, and direct-mail operations. They reliably contain documents, catalogs, flat-pack media, sample kits, and similarly dimensioned items that need the rigidity of corrugated construction rather than a poly mailer or padded envelope.

Each bundle contains 50 mailers. At approximately 0.44 lbs, they add minimal weight to outbound shipments, making them practical to stock in high-volume pick-and-pack environments. Bundles ship via parcel carrier.
