Which company is producing "eternal life pen" now?

Yongsheng pen factory has closed down 1999, and the brand has been merged into Hero's, but Hero did not produce it, but closed it down.

Later, Jiangxi Wengang has been known as the pen capital of China since ancient times, and some literati began to imitate immortality. Therefore, the eternal life pens below 10 yuan are basically from Wengang.
