Sewline Taylors Pencil Pink.
A modern mechanical pencil, just click to advance the 1.3mm lead-twice the thickness of standard fine leads. Clearly seen lines in pink. So much sharper and cleaner than chalks. No gritty or powdery residue. Erase easily with water or a polymer eraser. The rubberised barrel is comfortable to hold and enables a clear view of what is to be marked. This disposable pencil gives a substantial length of line while saving the trouble of stopping to sharpen.
