A high-resolution photograph featuring a small, rustic cloth sack filled with tiny black charcoal pieces. The sack, made of rough, natural fabric with visible stitches and a neatly folded top, stands out against a pure white background. The black charcoal pieces are much smaller, contrasting sharply with the light cloth. The lighting is bright and clear, illuminating the entire scene evenly, and highlighting every detail of the charcoal and fabric textures. The overall look is clean, minimal, and crisp, drawing attention to the natural elements of the sack and its contents.
