The proven mechanical pencil TK-Fine 1306 mechanical pencil 0.7mm is ideally suited to precise drawing. Users can choose between four line thicknesses: the 0.35 mm lead for extra fine drawing, the 0.5 mm lead for fine drawing, the 0.7 mm lead for particularly break-resistant drawing or the 1.0 mm lead for extra wide drawing. The lead can of course be fully retracted.
