What's the difference between a dip pen and a pen?

The difference between a dip pen and a pen lies in whether there is a "tongue" (a plastic hinge-like object under the tip of a fountain pen to discharge the ink in an ink bag to the tip) and an "ink bag". But what really affects the feeling of writing is the "tongue". Most fountain pens are made of tongue and nib, which makes the nib difficult to deform, so the written handwriting and lines will not change much (especially "bag-tip"). However, some high-end fountain pens with higher prices will take into account the changes of pen tip lines, so it can be said that it is difficult for most fountain pens to write beautiful "strokes". On the contrary, it is difficult to write beautiful "strokes" because of the ink sac, which is not limited by the tongue and the external coating structure of the pen tip, and because of the material of the pen tip, they can easily write lines with various thicknesses and beautiful strokes (some pen tips have different designs for different purposes, The structure and elasticity of the pen tip), so some English calligraphers especially like dipping pens. The pen tip of a dipping pen can generally be replaced, and it can be replaced at will according to the use requirements and the need to replace the old pen tip. In addition, the general dipping pen is much cheaper than the fountain pen, which means that you can write "the same beautiful words" at a lower price. However, because the dip pen does not use ink storage devices such as ink bags, it needs to be dipped in ink frequently. Although there are small objects such as ink reservoirs that can prolong the writing time, they can't compare with fountain pens, so the user group of dipping pens is relatively small. The above is the comparison between "dip pen" and "fountain pen".
