Black outline logistics icons on white background

Four simple black line icons are arranged in a clean two-by-two grid on a white background. The set includes a shipping container, a forklift, a barcode symbol, and a box on a pallet, suggesting warehousing, inventory control, and freight handling. Thick outlines and generous white space give the illustration a crisp, minimal look that works well for logistics, supply chain, and packaging themes. The composition feels like a vector icon sheet rather than a finished scene, with each symbol isolated for easy reuse in layouts, presentations, or app interfaces. High contrast and uncluttered framing make the graphic readable at a glance.
