The BSC PREFERRED MFL20204 is a white corrugated document mailer box built for maximum protection of flat documents, certificates, prints, and similar materials. Constructed from 200/ECT-32-B corrugated board, the box includes protective side flaps and a front outside tuck closure that locks contents securely without tape, glue, or staples. The design allows fast assembly in seconds, making it well suited for shipping departments, office environments, and fulfillment operations that need a reliable, tool-free mailer solution. Each pack contains 25 units.
This mailer is designed for shipping and storing flat, rigid, or semi-rigid documents that require protection from bending and crushing during transit. The front outside tuck closure combined with side flaps provides full enclosure on all critical edges. The white exterior is standard for professional document shipments. Packaging and shipping operations in office supply, legal, architectural, and general business environments are the typical install and deployment context for this product.
Designed as an OEM-style equivalent to part number S-2738. Suitable as a direct replacement or substitute in any application currently using that part.
No tools are required to assemble this mailer. Fold along pre-scored lines, tuck the front closure, and engage the side flaps before inserting contents. Ensure contents fit flat within the interior dimensions to avoid stressing the closure. Store flat in a dry location to maintain board integrity prior to use.
