This Black 0.5mm 600 Mechanical Pencil by Rotring features a full metal barrel that has been crafted in Germany to provide optimal balance of weight while writing. A fixed lead guidance sleeve prevents breakage and offers the artist a complete view of the paper for precise drawings. The metal barrel is designed in a hexagon which keeps the pencil from rolling on flat surfaces and the metal knurled grip provides traction when holding. Additional features are an adjustable lead hardness indicator as well as the built-in eraser. Loaded with high-polymer HB leads.
