12 x 9 x 3" Flat Corrugated Boxes

The 12 x 9 x 3 inch corrugated box is a single wall carton built from ECT-32 kraft corrugated board. The 3 inch depth is the defining feature here — it creates a snug fit for flat and shallow contents that would shift or require excessive void fill in a taller box.

This box fits naturally into e-commerce fulfillment, retail distribution, and light manufacturing environments. It handles apparel, books, documents, small electronics accessories, folded textiles, and similar low-profile products that need a carton matched closely to their dimensions.

Each box weighs 0.38 lbs and ships flat for compact storage. Boxes are sold in bundles of 25 and ship via parcel carrier.
