This 0.7 mm mechanical pencil features a full-metal silver barrel designed for precision technical work. The balanced weight distribution reduces hand fatigue during extended drawing and writing sessions. The brass mechanism delivers smooth lead advancement while the adjustable lead hardness grade indicator helps you quickly identify your settings. Its hexagonal barrel prevents rolling and keeps the pencil exactly where you position it during detailed work. The sliding sleeve provides excellent break resistance and a clear view when using rulers or straightedges. A non-slip knurled grip offers comfort for frequent use, and a built-in eraser sits neatly under the push-button cap.
