A brass flat bar, round bar, angle brass, square brass, and hexagon brass are displayed side by side, each with a polished golden-brass finish that reflects light. The flat bar has a wide, thin rectangular profile, while the round bar is a smooth cylindrical rod. The angle brass forms an L-shape with sharp edges, and the square brass has a uniform, four-sided profile. The hexagon brass features six equal sides, giving it a distinct geometric appearance. Set against a neutral background, the metallic sheen and textures of each shape stand out clearly.
