The Pentel N50XL Black is a new addition to the N50 Family permanent marker. This robust permanent marker will write on almost any surface, including wet and oily surfaces, offering maximum performance you can rely on every day. It features a strong aluminum barrel, perfect for long-lasting use in harsher working environments, and durable tips suitable for rough or smooth surfaces. The N50XL has a broad chisel tip that creates variable line widths of up to 17mm. The marker is made of quality material, has a hard-wearing chisel tip, and is permanent and waterproof. The UK's favourite permanent marker, it boasts a robust aluminum barrel and a bonded fiber tip that retains its shape. It will write on almost any surface, including cardboard, metal, wood, plastic, and glass. The tip measures 15.4mm x 11mm, giving a line width of up to 17mm. Unlike most alcohol-based markers, the N50 contains heavy-duty solvent-based ink, ideal for serious industrial use. It will write on wet or greasy surfaces where other markers fail, drying instantly and permanently.
