The pre-scored grooves allow easy folding to eleven different heights, offering multi-depth storage and enhancing product protection during handling and transit.

These A3 adjustable cardboard boxes are perfect for busy industries like retail and e-commerce, where presentation and efficiency are paramount. The crash lock base ensures swift assembly without the need for additional tape, allowing for quick packaging processes in high-volume situations.
