2-in-1 Metal Compass Set with Automatic Pencil, Geometry Drawing Tool, and Precise Portable Storage Box for Students, Math, Art & Engineering

This compass set integrates a drafting compass and mechanical pencil mechanism within a composite frame of metal hardware and ABS plastic. The combined tool structure supports routine circle drawing, geometric line creation, and mathematical drafting tasks. 1. Constructed from metal components and ABS materials to maintain structural integrity and reduce wear during regular handling. 2. Measures approximately 13.5 cm in length and 3.5 cm in width, providing a compact profile for easy transport and storage. 3. Packaged with a clear portable case that holds the main instrument and one pencil lead to prevent component loss. 4. Designed for mathematics coursework, technical drafting, and general design layouts requiring consistent geometric figures. 5. Equipped with stable metal pivot pins to enable steady rotation and controlled radius settings during manual drawing exercises.
