In 1822, the first ever propelling pencil was invented and patented by Sampson Mordan. From that point onwards the family-run business continued to develop its unique design carrying twelve three inch leads inside the barrel of the pencil, hence the name Yard-O-Led. In 1934, the Yard-O-Led Company was founded and today continues its traditions of craftsmanship and excellence established nearly 200 years ago. Each pen is individually numbered and comes complete with a lifetime guarantee.
