Use tutorial

1. Before getting the new pen, shake the pen body up and down several times to mix the ink evenly in the closed Hall.

2. Press the pen head down for a few seconds and then let go so that the air in the pen tube can be released (the new pen is in a completely sealed state, and the pen tube has a large amount of air in memory, excessive pressure will cause a large amount of ink to spray out during use)

3. Please put the pen back to cap of a pen for storage after writing, and put it horizontally in a cool place.
