The BSC PREFERRED M993K is a kraft corrugated literature mailer designed for shipping and storing flat documents, catalogs, and printed materials. Built from 200/ECT-32-B corrugated board, this mailer provides rigid protection without the bulk of a standard box. The self-locking design assembles in seconds with no tape, glue, or staples required. This SKU is sold as a pack of 50 units, making it a practical choice for mailrooms, distribution centers, shipping departments, and facilities teams that move high volumes of flat media on a regular basis.
This mailer is suited for light commercial and industrial shipping applications where documents, brochures, blueprints, or flat printed goods need secure transit protection. The kraft corrugated construction handles standard postal and courier handling. The pack-of-50 format supports bulk shipping operations and recurring dispatch workflows. Facilities managers, shipping coordinators, and supply room staff are the primary users of this product.
Designed as a standard literature mailer compatible with flat document shipping via common postal and courier services. Equivalent to part number S-16649.
No tools are required to assemble this mailer. Fold along the pre-scored lines and lock the self-closing tabs before inserting contents. Ensure the document or material fits flat without folding to maintain the integrity of the corrugated walls during transit. Store unused mailers flat in a dry environment to prevent moisture absorption that can weaken the board.
