These 4-3/8" x 4-3/8" x 2-1/2" white corrugated mailers are built from ECT-32-B corrugated board and close securely without tape, glue, or staples. The one-piece design folds flat to a finished mailer in seconds, with the folded structure forming double walls along the front and sides for crush resistance during transit.

The white exterior finish supports clean, retail-ready presentation, making these mailers a practical choice for e-commerce brands, subscription box operations, cosmetics fulfillment, and direct-to-consumer gift shipments. Their compact footprint suits small, rigid items such as jewelry, cosmetics compacts, USB drives, and folded documents.

Each mailer weighs approximately 0.13 lbs, keeping added package weight minimal. Constructed from ECT-32-B corrugated board, they deliver the rigidity of corrugated at a lightweight profile. Sold in bundles of 50 and parcel-friendly.
