12 x 3 x 3" Long Corrugated Boxes

This 12 x 3 x 3 inch corrugated box is built from ECT-32 single wall kraft corrugated board and features a long-side opening that provides unobstructed, full-length access to the interior during loading — a practical advantage when packing slender or elongated items that resist top-loading.

The slim profile suits posters, dowels, curtain rods, rolled documents, pens, cosmetic brushes, and similarly shaped products moving through e-commerce fulfillment, retail distribution, and light manufacturing. The long-side opening also benefits kitting operations where consistent, repeatable packing motions improve line throughput.

Each box weighs approximately 0.15 lbs and ships flat. ECT-32 construction delivers reliable stacking strength and puncture resistance for standard parcel transit. Boxes are sold in bundles of 25, and the flat-pack format conserves shelf space between replenishment cycles.
