Alvin’s Draft/Matic fine-line mechanical pencils are designed to provide the maximum professional convenience. This cushion pointed pencil has metal diamond-cut finger grips at top and bottom. A push button cap provides continuous feed of up to 12 leads and also conceals a built-in eraser. A rotating window indicates the degree of hardness of the lead being used. A 4 mm guide tube supports the lead and assures accuracy with even the thickest straightedges.
