The differences between straight liquid pens and gel pens are: 1. The writing fluency is different; 2. The ink is different; 3. The ink output control method is different.
1 The writing fluency is different:
Compared with gel pens, straight liquid pens can write more smoothly, without ink leakage, continuous ink, and no light ink when writing.
2 different inks:
The ink of the direct liquid pen is super-viscosity water-based ink, and the ink of the gel pen is cut by the ball to reduce the viscosity of the ink, and the viscosity is a medium-viscosity ink.
3 different ink control methods:
The uniformity of ink output is adjusted by the front ink controller of the straight liquid pen, while the ink output of the gel pen is directly controlled by the tip of the nose.
