Product Description

The BSC PREFERRED M666K is a pack of 50 kraft corrugated mailers designed for shipping small, lightweight, and fragile items while keeping postage costs low. Built from 200/ECT-32-B kraft corrugated board, these mailers fold to create double walls of protection on the front and sides, providing crush resistance without adding unnecessary bulk.
