A three-in-one bottle is a combination of an ink bottle, an inkstone and a pen container. Characterized in that the top of the bottle body is provided with a closed plane, and the plane is provided with an inkstone pool which is sunken downwards. There is a funnel-shaped ink outlet near the inkstone pool. There is a bucket with a one-way valve at the bottom in the ink outlet, and there is a pen container at one side of the bottle wall.
In feng shui, the function of three-in-one bottle is to help transport, but it pays attention to a lot.
