According to Support PD, the pen will be available for sale individually from October. The power adapter will probably also be available. I assume that Digitec will also sell them then.

I dropped the pen and damaged the tip. The screen still reacts when the pen is approached, so the pen itself still works. However, the tip is damaged and would probably scratch the screen surface. Are there replacement tips for the stylus? Or can I use one from the Microsoft Surface? If so, what is the article number?
