Compared to mass-market pencils, Osterling's entry-level mechanical pencil offers mechanical quality for a more accurate, dependable writing experience. Accurate lead advancement is provided by a brass mechanism. Plastic bodies are manageable and lightweight. Even on slanted drafting tables, the hexagonal barrel guarantees fatigue-free writing and drawing and keeps the instrument from rolling. Texturing aids in giving a solid grip. For accurate ruler-based drawing, a fixed lead guidance sleeve provides an unhindered page view and guards against breakage. When working, the lead hardness grade indicator makes it easy to quickly identify pencils. Designed in Japan
