The proven mechanical pencil by Faber-Castell - the TK-Fine Vario L is ideally suited to precise drawing. Users can choose between four line thicknesses: the .35mm for incredibly detailed 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.
