The Filzaufsätze - (Hard Felt Nibs)
To write better than the standard nibs, but not my favorite.
The spring essays - (Stroke Nibs)
Pleasant to Schreibem - Perfectly fit
Rubber articles - (Flex Nibs)
Very pleasant when Schreibem - my favorite.
Through the rubber in the middle of the resistance increases on the tablet. So I have the pen under better control.
The two rubber grommets can strip pin via the Wacom, stops just mediocre good and must be removed for transport.
The work on x230t has become so simple. For my big hands but I might still need a thicker pen - a Intus 4 perhaps that should be compatible.
The peaks, however, are great !!!
