The design features include:

1. Single Material and Easy Disassembly: The box body is made from a single material and uses easily detachable fasteners, making it convenient to recycle at the end of its lifecycle.

2. Stackability and Efficient Transport: The textured surface design and corresponding concave-convex patterns on both sides make the box easier to stack without tipping over, and save on shipping volume, indirectly reducing carbon emissions.

3. Low-Carbon and Plastic Reduction Design: The box weight has been successfully reduced by 20%, lowering carbon and plastic use without affecting its load-bearing capacity.

4. Innovative Appearance: The design features curves that represent ocean imagery, diamond-patterned textures that reflect the glitter of seawater, and the color of seaweed, breaking the stereotype of dark-colored marine waste products. This creates a look that is entirely different from the traditional black, rigid toolboxes, enhancing the sensation of visual and tactile, and fully embodying the spirit of sustainability.
