Notes
1. Please shake the dual pens before first using and after a long time using. Keep the pen straightly in order to make it run smoothly.
2. Please force press the brush tip and blends ink with water to soften tips before first using.
For optimal performance please ensure the marker caps are secure when they are not in use.
3. Please do not pull the cap directly and roughly, since the different air pressure inside and outside the caps may lead the ink to leak out.
