Partners Brand M551 Corrugated Mailers

The Partners Brand M551 Corrugated Mailers are white shipping containers designed for small, flat items that need rigid protection. Each bundle contains 50 mailers suitable for documents, photos, or slim merchandise. They serve home-based sellers, offices, and anyone mailing lightweight goods that must stay unbent.

Corrugated construction and self-seal convenience

The corrugated fibreboard walls resist crushing while keeping the package light enough for standard letter rates. A peel-and-seal closure removes the need for tape or staples, so packing stays quick even during high-volume sessions. The 5 by 5 by 1 inch footprint fits into most outgoing mail slots without extra handling.

Check your contents and postal rules before ordering

Verify that the items you ship sit comfortably inside the 1 inch depth without bulging the seams. Confirm that your postal service accepts this thickness for the rate you plan to use, as some carriers treat rigid mailers as parcels. Buyers sending thicker products or irregular shapes will need a deeper box or padded envelope instead.
