Deluxe Literature Mailers for flat items

These mailers measure 20 by 20 by 4 inches and come in a pack of 25. They suit offices or shippers sending flat documents, artwork or catalogues that need rigid protection. The white exterior presents a clean, professional appearance. Buyers handling thicker parcels should look elsewhere.

Check your contents and shipping rules

Verify that the items you plan to send fit within the 20 by 20 by 4 inch interior before ordering. Confirm that your carrier accepts this package size for the service level you intend to use. The pack contains 25 units, so ensure you have storage space for the bundle. No restricted states apply to this product.

Rigid construction holds shape under stacking

The deluxe build keeps corners square when boxes are stacked in transit or on a shelf. Contents stay flat without creasing even after prolonged pressure. The white surface resists scuffs during repeated handling. This mailer is not designed for heavy or irregular objects that could deform the walls.
