Fill the pen with water or immerse the pen tip in water and let it absorb water automatically, then the child can draw freely on the canvas; (When you use it for the first time, please screw the pen tip out, and immerse it in warm water for 30 minutes, so that the pen tip can be fully moistened and get expanded. The water will flow out more fluently when you fill it with tap water or drinking water and write with it later;)
The handwriting will appear immediately after the painting;
With the evaporation of water, the handwriting will disappear, and the canvas will get back to what it was, thus the child can continue to draw or doodle; (Note: the water stains may get dry fast or slowly, which depends on the dryness of the environment. It usually takes 5-10 minutes to get dry in summer, while it depends in winter since the indoor temperature differs greatly. Traces may be left on the edge of the painting due to the yellowed water in some places and it won't affect use. And the accumulated traces can be cleaned up with clear water.)
Please empty the water in the brush and dry it before you store the water drawing cloth book.
