These 5 x 5 x 2  kraft corrugated mailers are built from ECT-32-B single wall corrugated board in a one-piece fold-together construction. The folding geometry creates double wall thickness along the front and sides, reinforcing the enclosure with no tape, glue, or staples required.

The self-locking design supports fast pack-out in e-commerce fulfillment, subscription box operations, retail distribution, and light manufacturing environments — anywhere compact, low-profile items need crush-resistant protection without added assembly steps. At 0.12 lbs, the lightweight build also helps control dimensional weight costs on high-volume outbound shipments.

Mailers store and ship flat, preserving rack and floor space until needed. Each bundle contains 50 mailers and ships via parcel carrier.
