When we write for a long period of time, our hand often grows tired from having to grip a pen. The excessive force used in holding a pen can also damage the pen tip and the paper. This pen solves that problem, equipped with a magnetic buffer device at the neck of the pen. The magnets repel the same pole to alleviate hand pressure. When writing with normal force, the repulsive force maintains the position of the refill. When too much pressure is used, the bottom magnet is pushed upward to generate mutual repulsion with the upper magnet. This effectively absorbs the pressure of the pen tip to protect the pen tip and paper.
