Product Description

The BSC PREFERRED RM3 is a stayflat chipboard mailer designed to protect photos, documents, and other flat, rigid items during transit. Constructed from 0.036-inch kraft chipboard, the mailer provides firm, consistent rigidity without requiring additional stiffeners or inserts. The tab lock closure secures contents without tape or staples, speeding up packing workflows. Lightweight construction keeps postage costs down. Each case contains 100 mailers, making this a practical choice for shipping departments, fulfillment operations, and document-heavy businesses that process high volumes of outbound mail.

The RM3 mailer is suited for mailing or shipping flat items such as photographs, certificates, artwork prints, contracts, and similar documents that require protection from bending or creasing.
