The pen consists of a nib, an ink bag, a handle, a pen holder and a water supply/ink storage mechanism. The nib can be said to be one of the most critical parts of the pen, which varies from fine to thick. The common pen tip sizes are "B, M, F, EF", and from coarse to fine is B >; M>F & gtEF, pen tip size Each pen factory will have some differences in specifications. Of course, this is inevitable and normal.

According to the usual writing habits, Westerners usually use M-tip as the main pen and choose B-tip when signing. Due to the complexity of Chinese writing strokes, M, F or thinner EF pen tips can generally be used. If you want to have a reference, the font written by F-tip is similar to that of a 0.5 mm carbon pen.

According to the survey, the medium M-shaped (0.5-0.6 mm) pen tip is more suitable for signature, and it is easy to produce results in a short time with supporting measures. The design of domestic nib is slightly smaller than that of European nib, that is, the thickness of m is similar to that of European nib.

Precautions:

Although the ink bag is inside, it doesn't need to be touched by hand in the process of writing, but its performance also plays an important role in the effect of writing. If the amount of ink inhaled at one time is small, it needs to be sucked frequently, which will not only have a bad influence on the life of the ink bag, but also have a certain influence on the continuity of writing, which will eventually lead to poor writing effect.

According to statistics, there are three kinds of ink capsules of popular pens in China, namely, the pen barrel type, the needle tube type and the spiral type. Because the pen bag type is more in line with the user's habits and easy to use, nearly two-thirds of the ink bags in China are pen bag type.
