When replacing ink, it is very convenient because it can be replaced from the pen tip.
When the ink runs out by people, the pen tip is also thick, and fine characters are difficult to write, so I thank you very much.
Writing pressure has individual differences, but it is convenient because it can be replaced from the pen tip even if it is dented.
The ink is not reduced little by little, it will suddenly become impossible to write if it is lost, "Can you write a little more?" Since I do not need to get lost as to whether to replace it, I always use this marker in the company ☆
