Thickness pens for writing beginners, slim for pros? But why? If yes fillers applies rather opposite, that the most expensive precious writers often offer more hands-on. I have these pencils met through my writing learning daughter and find it quite enjoyable also for their own use. Only that there are no decent sharpener and do not fit these pins in normal sharpening machines cost a star but strictly speaking that is actually not at these pencils but on immature accessories.
