Usually, we call this type of pen a "whole needle tube". The key difference between it and the head type of a bullet is that it is made from a non cutting process. Before processing it, it is a complete thin tube. Through precise instruments, 3 concave points are formed from 3 directions at the front end of the thin tube, forming the bowl holder of the ball beads, while the latter is triangular oil groove. The ink is out through the oil tank and the ball is rolled out through the ball of the ball to finish the writing process. The needle tube type is suitable for making fine brush, such as 0.30, 0.25 and so on.

The semi needle tube is between the bullet and the needle tube, and the shape is more beautiful. The tip of the pen can be as thin as a needle tube, and the end of the pen is as big as the tail end of the bullet. The semi - needle type can make relatively fine brush, such as 0.48, 0.35, etc.
