Protect your Apple Pencil
In Order to protect the tip of your Apple Pencil you can use a cap of a standard ink roller. I spent an hour in our local department store and tested a lot of different caps.
Here is the one I can recommend:
Don't put the Schneider cap on the backside of the Apple Pencil at the Cap that protects the Lightning connector. The smaller Lightning-cap might get trapped inside the Schneider-cap.
