You are purchasing the Wacom Pro Pen 3. It includes the customization pieces as well as a thing you can place inside the pen in lieu of the weights that can store spare nibs. The only thing missing is a panel with no buttons you could use if you’re using with the grips. It works amazing. The only reason why I’m selling it is because I just don’t use it and I’d rather it be used by someone than gather dust. Any questions, by all means ask
