A Copper Bar in Black Desert Online is a medium-sized, rectangular metal ingot with a smooth, slightly reflective surface that showcases its metallic sheen. The bar has a rich, warm copper color with subtle variations in hue to indicate its purity, and it may feature small, irregular edges or slight imperfections from the smelting process, adding to its realistic appearance. The bottom surface is flat for stability, while the top may have a slight convex curve, with possible faint hammer marks or casting lines for added detail.
