The Sharpie Magnum Permanent Marker (Model 44001A) is a heavy-duty, oversized marker designed for large-scale marking jobs. It features a broad chisel tip that delivers extra-wide marks, making it ideal for labeling boxes, pallets, lumber, and industrial materials.

The marker's ink is permanent, quick-drying, and resistant to water and fading. It writes on a wide variety of surfaces including plastic, wood, stone, metal, foil, corrugate, and leather, and can mark through wet, greasy, or oily surfaces. The durable aluminum barrel and reinforced felt tip are built to withstand heavy use. The extra-large ink reservoir provides a significantly longer-lasting supply compared to standard permanent markers.
