The Diplomat is the original Yard O Led Pencil, containing the yard of lead to which the brand became known. It was designed with a hexagonal shape so that it wouldn’t roll off a draughtsman’s table, and features Victorian detailing such as the curved clip with visible screws. Available as a ballpoint pen which comes with a blue ink refill, and a pencil which fits a 1.18mm lead. The Diplomat is individually numbered and comes with a lifetime guarantee. Additional refills available here.
