Easy-Fold Mailers for Flat Items

These white mailers measure 12 by 9 by 3 inches and fold easily around documents, catalogues or small boxed goods. The pack contains 50 units, making them suitable for regular office dispatch or e-commerce fulfilment. They arrive new and ready to use without assembly.

Paper Construction Limits Protection

The flat paperboard design protects against creasing and minor impacts but does not cushion heavy or fragile contents. Items thicker than the 3-inch depth will not seal properly, and the material is not rated for moisture resistance or extreme handling.

Simple Fold-and-Seal Assembly

Each mailer ships flat and folds into shape in seconds, then seals with tape or an adhesive strip. The most common issue is overstuffing, which prevents the flaps from closing flat and can cause the seams to split during transit.
