Bsc Preferred M644 Corrugated Mailers White Pack of 50

Product Description

The BSC PREFERRED M644 is a white corrugated mailer designed for shipping small, lightweight fragile items without tape, glue, or staples. Constructed from 200/ECT-32-B corrugated board, these mailers fold to create double walls of protection on the front and sides, delivering crush resistance while keeping package weight low. Sold in packs of 50, the M644 is a practical choice for shipping departments, fulfillment operations, and any trade or supply business that moves small parts and components regularly.

The M644 mailer is suited for residential and commercial shipping applications where a secure, self-sealing enclosure is needed for fragile or small-profile items. The fold-over design eliminates the need for additional sealing materials, streamlining the pack-and-ship process. Each pack contains 50 individual mailers, making it practical for moderate-volume shipping operations.
