6 x 6 x 4" Multi-Depth Corrugated Boxes

These 6 x 6 x 4 inch multi-depth corrugated boxes are built from ECT-32 single wall kraft corrugated board and feature pre-scored side panels that let packers fold the box down to a shorter depth at the score lines. Adjusting height requires a cutting tool at the corners — no carton sizer needed — making the conversion quick at the packing station.

The adjustable depth makes these boxes a practical fit for e-commerce fulfillment, retail distribution, subscription box operations, and warehouse shipping departments where product heights vary across orders. Collapsing the box to match actual product height reduces void fill consumption and helps control dimensional weight charges on outbound parcel shipments.

Each box weighs approximately 0.18 lbs, keeping bundle weight manageable for high-volume lines. Sold in bundles of 25, these boxes allow operations to consolidate inventory by replacing several fixed-depth sizes with a single SKU that accommodates variable-height products.
