8k hard pen calligraphy paper price

For sketching 8K and 16K paper, it is actually possible, but the picture is small and easy to control. So 16K may be better controlled.

There are also differences between pen-and-ink painting. Ink painting has only one line with different thickness, while art pen can draw at least three lines with different thickness by using the center, side and back.

Moreover, pen drawing is not necessarily a single line, and it can be as bright and dark as charcoal drawing, but the tone is different from charcoal drawing.
