Yard-O-Led Diplomat Ballpen – A British Classic Since 1934 Timeless and refined, the original Yard-O-Led Diplomat Ballpen is a true icon of classic British design. First introduced in 1934 and awarded its patent the same year, the Diplomat remains one of the world’s most renowned writing instruments. Crafted from hallmarked sterling silver, each ballpen is individually numbered and handmade in Yard O Leds Birmingham workshop, just as it was over 90 years ago. Its distinctive hexagonal barrel isn’t just elegant — it was purposefully designed to remain stable on sloped surfaces like a draughtsman’s table, combining form with intelligent function. Unchanged in design since its creation, the Diplomat Ballpen reflects the enduring quality, precision, and craftsmanship that Yard-O-Led is known for. A legacy in your hand — the Diplomat is more than a pen. It’s a piece of history.
