Store your pens so that the nib is not experiencing constant pressure. Some tablet users suggest that if the nib has a constant pressure applied to it, over time the pressure could damage the pressure sensor.
If you pen came with a case designed for it, that is the safest place to store it. These cases provide a lt of protection for the entire pen and the pressure sensor
In the photo below you can see how a case has extra room for the nib so nothing can press into it.
Below, three conceptual options are presented for storing a pen.
The one on the far right places no load on the pressure sensor
The one on the far left places the entire weight of the pen on the pressure sensor
The one in the middle places only the weight of the nib on the pressure sensor. This is the way I store my pens.
