The choice of pen tip varies from person to person, and different shapes and thicknesses may affect everyone's writing experience. Here are some pen tip types that may be suitable for different people:

* thickness: the thickness of the pen tip is different. Common types from fine to coarse are EF (superfine), F (fine), M (medium coarse), B (coarse) and BB (double coarse). Generally speaking, people with light hands or small handwriting are suitable for choosing a thin nib, while those with heavy hands and thick handwriting are suitable for choosing a wider nib.

* Tip shape: In addition to thickness, the shape of the tip will also affect the writing experience. Some pen tips may have special shapes, such as inclined tips (such as OM, OB, OBB), which are suitable for special writing needs or personal writing preferences.

* Material: The material of the nib will also affect the writing experience. Common materials include steel and gold. The nib is relatively cheap and durable, while the golden nib is softer and more elastic to write, but it is more expensive and easy to deform.

Generally speaking, choosing a suitable pen tip type depends on one's writing habits and preferences. It is suggested that before buying, try different shapes, thicknesses and materials to find the one that suits you best.
