7 x 7 x 3" White Corrugated Mailers

These 7 x 7 x 3 inch white corrugated mailers are built from ECT-32-B single wall board and feature a one-piece self-locking construction that closes without tape, glue, or staples. The folded design reinforces the front and sides with double wall thickness, delivering crush resistance during transit while eliminating the need for additional sealing materials or assembly steps.

The clean white exterior supports retail-ready and branded fulfillment presentations, making these mailers a practical fit for e-commerce operations, subscription box programs, boutique retail distribution, and direct-to-consumer cosmetics or hard goods shipments. The interior footprint are well suited to books, boxed gifts, photo prints, small accessories, and similarly flat or low-profile items.

Each mailer weighs approximately 0.25 lbs, keeping dimensional and actual weight costs manageable at high volumes. The mailers are parcel-friendly and sold in bundles of 50.
