13 x 13 x 3" Flat Corrugated Boxes

These 13 x 13 x 3 inch corrugated boxes are purpose-built for flat and low-profile products that would shift or compress inside a standard-depth carton. The 3 inch depth keeps contents snug without excess void fill, making these a practical choice wherever shallow containment is a priority.

Common applications include apparel folded flat, framed artwork, ceramic tiles, board games, document mailers, and kitted components in retail or e-commerce fulfillment. The square 13 x 13 inch footprint suits products that are as wide as they are long, such as vinyl records, fabric swatches, or flat-pack hardware kits.

Each box is constructed from ECT-32 single wall kraft corrugated board, providing reliable stacking strength and puncture resistance. Boxes ship and store flat, reducing warehouse footprint until needed. Sold in bundles of 25, each unit weighs approximately 0.61 lbs.
