9 x 9 x 3" White Literature Mailers

These 9 x 9 x 3 inch white literature mailers are built from ECT-32-B single wall corrugated board and feature an integrated tab-lock closure that secures without tape, staples, or additional supplies — reducing pack time and eliminating the need for secondary sealing materials at the station.

The clean white exterior suits retail distribution, direct-to-consumer fulfillment, B2B document shipments, and brand-forward packaging for promotional kits, media, and light manufactured goods. The square footprint is particularly well matched to apparel inserts, printed materials, and flat accessories where a standard rectangular box would leave excess void space.

Each mailer weighs approximately 0.30 lbs and ships via parcel carrier. Sold in bundles of 50, sized to stage neatly at packing stations without consuming significant shelf or floor space.
