These 21 3/8 x 15 5/8 x 12 5/8 inch corrugated boxes are built from ECT-32 single wall kraft corrugated board, delivering consistent stacking strength and puncture resistance suited to mid-size, heavier-content shipments. Interior dimensions provide the full stated clearance for product and dunnage.

The footprint and depth make these boxes a practical choice for e-commerce outbound fulfillment, wholesale distribution, retail replenishment, and manufacturing parts shipment. They accommodate standard void fill, layer pads, or tissue wrap without modification, and the rectangular profile works efficiently on packing lines where consistent box sizing reduces variability.

Each box weighs approximately 1.493 lbs, and the single wall construction meets standard requirements for this size class. Boxes are sold in bundles of 20 and ship via parcel carrier.
