These 5" x 3" x 1" white corrugated mailers are manufactured from ECT-32-B corrugated board and fold into a finished, locked structure without tape, glue, or staples. The one-piece design reduces assembly time at high-volume pack stations while delivering a clean white exterior suited to both branded and unbranded outbound shipments.

The folded construction creates double-wall panels along the front and sides, making these mailers a practical fit for jewelry, flash drives, gift cards, cosmetic samples, small electronics components, and other flat or low-profile items. E-commerce fulfillment centers, retail distributors, and manufacturing operations all benefit from the consistent, tool-free closure on repeat runs.

Each mailer weighs approximately 0.07 lbs, keeping dimensional weight impact minimal on small parcel shipments. The ECT-32-B board provides crush resistance proportionate to the compact format. Bundles contain 50 mailers and ship via parcel carrier.
