How to remove the calligraphy pen

In the process of writing, the weight of the pen cap will affect the transportation of the pen. The pen cap should be put on the pen holder, and the hook of the pen cap should face the tiger's mouth hole, that is, the outward side.

The hook of the pen cap is upward, which ensures the balance of the pen from left to right and will not tilt.
