[how to use the dot flower pen]:
1. open the pen cap, the pen tip is the kind with high white hardness.
2. press down the pen tip (the pen tip is stretchable and can be pressed, similar to the meaning of a switch).
3. close the pen cap and shake it twice, and the color will stay on the tip of the pen.
[note 1]: If the water is not enough, you can close the pen cap and shake it twice, and each one will be water. If you do not have water, you can try several times.
