Bsc Preferred M12121 Corrugated Flat Mailer 50 Pack

Product Description

The BSC PREFERRED M12121 is a white corrugated flat mailer designed for shipping books, catalogs, framed pictures, and similar flat or semi-rigid items through standard mail and parcel carriers. Built from 200/ECT-32-B white corrugated board, it provides a clean, professional exterior finish along with reliable structural protection during transit. The mailer is scored at multiple depths, allowing the packager to set the box depth without any carton setup - simply center the item, fold in the sides to the needed depth, and seal with tape. Each pack contains 50 mailers. This format is widely used in mailroom, warehouse, and fulfillment operations.

This mailer suits residential and commercial shipping applications where flat or lightly padded items require a rigid, protective enclosure. It is commonly used by fulfillment centers, print shops, photographers, retailers, and office mailrooms. The self-adjusting depth feature reduces the need to stock multiple box sizes, making it practical for operations that handle a variety of item thicknesses. This product is equivalent to part number S-343.
