炭素鉛筆 : 學美術的人sketch用的
有沒有carbon pencil 您古狗一下呀
The carbon pencil is the perfect combination of charcoal and graphite. It has a fine grain, and goes on smoothly and precisely in rich, velvety, matte black lines. Carbon pencils have a consistent softness, for superior blending and texture.

普通鉛筆 is made of graphite and wood only.
