1. Structural Design: Integrated hinge combined with a dual-sided snap-lock mechanism ensures smooth opening and closing, with automatic locking upon closure to prevent accidental popping open; the box opening features a limiting protruding ring, and the interior cavity is finished with rounded corners, eliminating sharp burrs or edges; both sides of the box body are pre-equipped with axle-passing holes for mounting and securing rods.

2. Functional Applications: A compact internal compartment for storing electronic accessories, small hardware items, fishing gear components, jewelry, and other tiny parts; its portable size allows it to be carried on the go or mounted on a wall.
