The cover of the promotional brochure for HEX NUT, with green and blue color accents. The background is blurred, but the hand of a mechanic with a metric wrench is distinguishable, focusing attention on the product in the foreground. This design highlights various parts such as nuts, bolts, or fasteners. A close-up shot captures one part being held by two hands using that tool. The overall style resembles commercial advertising, conveying brand identity through visual elements like shapes with touches of architectural drawing.
