2.M tip is 0.7mm, which is the thickness of general writing. 0.7mm is no longer suitable for writing small characters, and can be used for writing large fonts or signatures. The difference between 0.7mm and 0.5mm is still obvious.
3. I have been using Schneider's drawing pencil, which is of very good quality and feels good, but I have never used this brand of pen. Like LAMY, Schneider is also a well-known brand in Germany. Generally speaking, the quality of German pens is very good. Although I haven't used it, just looking at this brand is very trustworthy. It is worth mentioning that, in terms of personal experience, I think German pens are slightly thicker than those in China and Japan. Because I write letters, I think EF pens are the most comfortable. If you still can't find Schneider's F-tip, I recommend buying LAMY's safari, and the price is similar to Schneider's.
