These 18 x 13 x 12 inch corrugated boxes are built from single wall ECT-32 kraft corrugated board, delivering reliable stacking strength and puncture resistance for everyday shipping and storage demands. Interior dimensions make product fit predictable and consistent across a packing line.

The footprint suits mid-size products commonly shipped in manufacturing, retail distribution, and e-commerce environments — including apparel bundles, auto parts, packaged foods, and consumer electronics accessories. The depth accommodates bulkier items that won't fit in a flat mailer or smaller RSC without overpacking.

Each box weighs approximately 1.162 lbs and is manufactured from recyclable kraft corrugated material. Cases are sold in bundles of 25, and the parcel-friendly size keeps replenishment simple for operations running standard small-parcel programs.
