With its unique line expression, it plays an irreplaceable role in sketch creation. Next, we will explore the unique role of the lining pen in sketching. Firstly, the line expression of the lining pen is very strong. It can delicately outline the contour and details of objects through fine lines. In sketching, the lining pen can easily depict the shape, structure, and texture of objects, making the picture more vivid and realistic.
