Oily pens include ballpoint pens, but do not include carbon pens.
The ink has high viscosity and long writing length, that is, more characters can be written under the same ink output, and it is fast-drying, water-resistant, soft and light-resistant, and the paper will not be damaged by repeated color superposition; The disadvantage is that the writing feel and quality are not good. Oil-based pen can be divided into thick and thin single head and double head, which can express the effect quickly and is one of the most important drawing tools at present.
The ink in the carbon refill is mainly composed of graphite, which is one of the most stable substances in nature. Therefore, writing with a carbon pen will not be blurred because it is kept for too long.
