These white corrugated mailers are built from ECT-32-B B-flute board, delivering meaningful crush resistance while keeping unit weight low — an important factor when postage is calculated by weight. The one-piece construction folds into a sealed mailer without tape, glue, or staples; interlocking flaps create double-wall reinforcement across the front and sides once assembled.

The square 4 3/8" x 4 3/8" footprint is well-matched to cosmetics, health and beauty samples, small electronics accessories, jewelry, and subscription box inserts. The clean white exterior presents a professional appearance on customer-facing shipments, making these a practical choice for direct-to-consumer e-commerce and retail replenishment programs.

Constructed from B-flute corrugated with an ECT-32-B rating, each mailer weighs approximately 0.14 lbs. Bundles contain 50 mailers and ship via parcel carrier.
