风箱一吹掀开的齿轮盒子

Centered on a plain pale surface, an immaculate, unmarked white box has its hinged lid lifting upward, still aligned with its rear hinge — the moment caught in crisp side light for this conceptual product shot. A small brass bellows with a plain wooden handle sits beside it, nozzle aimed straight at the lid seam, curling ribbons of dust rising from its tip to suggest the gust doing the work. Inside the box, a tangled dark mass of iron gears fills the cavity, meshing and overlapping in a dense knot that stays contained — nothing spills outside the box — and the contrast against the pristine white exterior makes clear this was hidden until the lid lifted. A side view holds the box, the bellows, and the exposed interior with clear margin inside the frame, nothing cropped at the edges; the surface stays plain, the backdrop bare, and no lettering appears anywhere. 16:9 wide composition.
