These 4 x 4 x 1 inch kraft corrugated mailers are built from ECT-32-B single wall corrugated board and close via a one-piece fold-together design that creates double walls on the front and sides — eliminating the need for tape, glue, or staples at packing stations.
The compact 1" depth makes these mailers well suited for jewelry, patches, stickers, small electronic components, coins, and other flat or low-profile items shipped through e-commerce fulfillment centers, retail distribution operations, and manufacturing facilities.
Each mailer weighs approximately 0.07 lbs, helping to keep dimensional weight low, and the flat-fold format stores efficiently on warehouse shelving. Bundles of 50 ship via parcel carrier.
