Precautions in use

Marking pens :How to store marking pens

There is time limitation of storage of marking pens. However, you can extend the use period by paying attention to the followings:
For ink-based marking pens, put the pens horizontally to keep an appropriate status. This is the best way to obtain the effect of keeping the dispersed state of the pigment in the ink in prevention of ink nib clogging. If the pen tip is upward, the ink density will be low at the tip. If it is placed downward, the density may be high in the pen tip that it may be jammed.
Besides, it is not good to storage it at high temperature, especially above 60°C at which the axis part might be influenced.
If the product gets hit from inside, please note that the filling may slip out and the ink may pop out.
