The third grade of primary school is in the stage of practicing calligraphy. First of all, 0.38 is too thin to enter the water well and it is difficult to write. But the third-grade students have a hard time writing, and 0.38 is too thin to cut paper easily. 0.5 is thicker than 0.38, which makes it easier to master writing and is conducive to students' writing practice.

The second point: Why not suggest using a ballpoint pen? The ink of ballpoint pen is very sticky. If there are bubbles in the middle, it is easy to break the ink and there will be instability. Signature pens or gel pens are the most stable.
The third point: Why should the thickness be above 0.5? Because the paper can't be very thin in the scanning process, if the handwriting is too thin, what you actually see on the screen will become intermittent, which will bring difficulties to the marking work and may not be clear.
