Zoro Select M743 Literature Mailer White 7x4x3 in 50 pack

Compact literature mailer for flat items

The Zoro Select M743 is a white corrugated cardboard mailer designed to ship documents, catalogues and slim products. Each unit measures 7 by 4 by 3 inches inside and uses a single B-flute wall rated at ECT-32-B. The pack contains 50 mailers, making it suited to offices, fulfilment centres and direct-mail campaigns that need a consistent, lightweight box.

Rigid single-wall construction handles stacking

The 3/16-inch B-flute board supports a maximum load of 65 lb, so packed mailers retain their shape on conveyor lines and in stacked pallets. Because the walls are single-wall rather than double-wall, the mailers stay light for postage savings while still resisting crush damage during sortation. The 100 percent post-consumer recyclable material meets typical corporate sustainability mandates without extra sorting steps.

Replaces improvised padded envelopes

Teams that currently stuff flat goods into bubble mailers gain corner protection and a crisp presentation; those using larger cartons cut void fill and dimensional-weight surcharges. The jump is worth it when your average shipment fits the 7x4x3 envelope and you process enough volume to justify a 50-count case. Buyers needing deeper boxes or heavier-duty double-wall board should look elsewhere.
