This vintage mechanical pencil features a twist design and has a lead diameter of 1.1 mm. It was made in the United States during the 1930s-40s era and is made of celluloid material. The pencil is 5 inches long and is in working condition, with lead already installed. This item is a great addition to any collection of vintage writing instruments. It may have an eraser but I can't take it apart. Sold as is. No brand name but does say "Made In USA."
