These 11 1/8 x 8 3/4 x 4 inch white literature mailers are built from ECT-32-B corrugated board — a B-flute single wall construction that delivers rigid protection in a lightweight footprint. The white exterior provides a clean, professional presentation without custom printing or added branding cost.

The tab-lock closure seats firmly within the carton walls, eliminating the need for tape, glue, or sealing tools at the pack station. This makes them a practical fit for publishers, legal and financial service providers, fulfillment centers, and direct-mail operations shipping catalogs, reports, booklets, and flat-packed documents at volume.

Each mailer weighs approximately 0.39 lbs, keeping parcel rate calculations favorable for ground shipments. Mailers are sold in bundles of 50 and ship via parcel carrier.
