Partners Brand 15 x 15 x 4 Corrugated Boxes

Best for shallow items such as apparel, books, picture frames, artwork, mirrors, and clothing. These boxes use 200#/ECT-32 kraft corrugated for sturdiness. Ideal for home or business use where bulk packing is needed. Best for buyers prioritizing a compact footprint and a strong single-wall box for lighter to medium loads. A limitation is less internal depth than deeper cartons, so tall objects may not fit.
