The pen needs running-in. I think the pen is like a swordsman's sword. If you use it for a long time, you will have feelings. Even if I give it to you no matter how good and expensive it is, you will feel that it is not as good as the old one. I used 1 1 year for my pen, and it was less than 10 yuan when I bought it, but I just think it is the best one. I wouldn't be used to anything else.
