In the past, children were accustomed to using pens to practice calligraphy. There are actually many advantages to using pens to practice calligraphy. But after the emergence of gel pens, calligraphy practice with gel pens has many new advantages over pen practice.
Through comparison, it is found that the effects of ordinary fountain pens and 0.5 gel pens are relatively close, but the lines of the gel pen appear smoother. This is because the pen tip of the pen has greater friction and the writing Line stability is slightly worse.
Gel pens are slipperier than fountain pens, so hold the pen loosely and don't waste any effort. The ink flow of the neutral pen is smoother, and the pen tip is strong and sturdy. You only need to add a writing pad to write lines with varying thicknesses and fat and thin lines. It’s not tiring to write either.
