These 12 1/2 x 12 1/2 x 2 inch white easy-fold mailers are built from ECT-32-B single wall white corrugated board and incorporate multiple score lines that let operators adjust depth (1/2", 1", 1 1/2", 2") before sealing. The fold-and-tape assembly requires no specialized equipment, making setup fast at any packing station.

The square footprint and shallow profile make these mailers a natural fit for books, framed prints, calendars, puzzles, and similarly flat or low-profile products. E-commerce retailers, subscription box operations, and B2B distributors rely on them for clean, professional direct-to-consumer and wholesale shipments alike.

Each mailer weighs approximately 0.35 lbs and is sold in bundles of 50. The parcel-friendly size supports straightforward restocking without special handling arrangements. Order single bundles or multiple units to align with your fulfillment volume.
