Description

New: A brand-new,unused
It is a pen tip that can draw the thickest line among the pen nibs, which makes it easy to adjust the strength of the line.
However, since it is easy to add strength, the control requires some getting used to. 
You can write thick lines without difficulty.
The strength and weakness of the line (strong is a thick line, weak is a thin line) means that you can write a thick line or a thin line depending on the angle of the pen tip and the amount of pressure applied.
These uses are for reference only, so please use them properly according to your drawing style and habits.
