1. Unique Material and Center - of - Gravity Design: The pen body is crafted from an innovative triple - density special material. Compared with ordinary gel pens, it has a significantly increased weight while maintaining a reasonable heft. Through precise structural design, the heavier parts are distributed at the bottom of the pen body, forming a low - center - of - gravity structure. When holding the pen for writing, it feels as if the pen naturally conforms to the hand, providing a strong sense of stability. Even during long - term writing, you can handle it with ease, reducing hand fatigue. This unique center - of - gravity design not only enhances writing fluency but also adds a special sense of pleasure and control to the writing process.
