The BSC PREFERRED M963BF is a self-adjusting corrugated flat mailer designed for shipping books, catalogs, framed pictures, and similar flat or semi-flat items. Built from 200/ECT-32-B white corrugated board, it provides a clean, professional exterior and enough structural rigidity to protect contents in transit. The scored construction allows the mailer to be set at multiple depths without cutting or folding extra material. No carton setup is required - place the item in the center, fold in the sides to the desired depth, and seal with tape. Each pack contains 50 mailers, making it practical for high-volume shipping operations.
This mailer is suited for e-commerce fulfillment, print shops, framing studios, and warehouse shipping departments that regularly send flat or lightly padded items. The adjustable depth scoring makes it versatile across a range of item thicknesses without stocking multiple box sizes. The white corrugated finish presents well for retail or direct-to-consumer shipments where presentation matters alongside protection. It is sold by the pack and is appropriate for both low-volume and repetitive shipping workflows.
Designed as a general-purpose flat mailer compatible with standard tape-seal shipping workflows for books, catalogs, and framed pictures in residential and commercial fulfillment environments.
No tools are required to set up this mailer. Place the item in the center of the flat blank, fold the scored sides inward to the desired depth, and secure all seams with pressure-sensitive or reinforced packing tape. Ensure the selected depth setting fully encloses the contents before sealing to prevent shifting during transit.
