The BSC PREFERRED M1666 is a pack of 50 white corrugated mailers built for shipping small, lightweight fragile items without added weight or bulk. Manufactured from 200/ECT-32-B white corrugated board, these mailers fold to create double walls of protection on the front and sides. The self-locking design requires no tape, glue, or staples, making them a fast and clean option for high-volume shipping operations. The lightweight construction helps keep postage costs down while still providing crush-resistant protection during transit.
These corrugated mailers are suited for warehouse operations, fulfillment centers, shipping departments, and any trade or distribution environment that requires reliable protective packaging for small parts, components, or fragile goods. The white corrugated finish presents cleanly and holds labels well. Each pack contains 50 mailers, making them practical for stocking at a shipping station or supply room.
Designed as a general-purpose corrugated mailer for shipping small, lightweight fragile items. This product is equivalent to part number S-10705.
No tools are required to assemble these mailers. Fold along the pre-scored lines and tuck the locking tabs to close the mailer before placing it into the mail stream or carrier system. Ensure contents are properly centered and padded as needed before sealing. Store flat in a dry environment to maintain board integrity.
