The M510 is the heavy-duty specialist of the Munhwa Pro Drafting series. Its distinctive yellow body signifies the 0.9mm lead size, which is highly favored by architects, contractors, and artists for bold sketching and technical marking. The thicker lead is virtually break-proof under normal writing pressure, providing a buttery-smooth experience on all types of paper. Like its siblings in the M-series, it features a precision internal clutch and a fixed guide pipe for professional accuracy. Proudly made in Korea, this pencil combines decades of manufacturing expertise with reliable durability.
