No idea about pens, but when I was her age my parents bought me a calligraphy set. My father taught me his version of calligraphy and I used to spend hours copying various alphabets. If she loves writing it might be worth thinking about?
My DD has a banana pen (stabilo curvy thing) they come in left and right handed and her prep school will only let them write in them as they help them keep neat writing when using a pen, they also help kids with their grip and not straining too much. They get them when they have earnt their pen licence
