Partners Brand M552K Corrugated Mailers Kraft 50/Bundle

50-piece Kraft corrugated mailer bundle

These Partners Brand M552K mailers ship flat and arrive new in a 50-count bundle. They are sized at 5 x 5 x 2 inches for small, rigid items that need crush protection. The kraft corrugated construction resists punctures and keeps contents secure during transit. Office mailrooms and e-commerce sellers can pull one mailer at a time without breaking down a larger case.

Lightweight kraft board keeps postage low

The single-wall corrugated walls add stiffness without the weight of double-wall stock. That means standard letter-rate or small-parcel postage applies for most domestic shipments. No foam inserts or bubble liners are included, so the package stays thin and flexible until you seal it. The natural kraft surface accepts tape, labels and marker ink cleanly.

Ships flat to free shelf space

Because the mailers arrive collapsed, a full bundle occupies only a narrow slot on a packing bench or shelf. You expand each mailer only when an order is ready, eliminating the need to store pre-formed boxes. The 50-count bundle is small enough to keep at a workstation, so there is no separate bulk-storage step. Buyers who need larger dimensions or padded interiors will need a different mailer style.
